👉 Dancing Drops by exploratorium: an exhibit employing the Coandă effect on water droplets -an air stream attaches and wraps around the drops temporarily trapping them. As the air changes direction to flow around a drop, momentum is imparted to it pushing the drop against gravity.
👉 Corner Cube Prism: a light ray entering a mirrored retro-reflecting prism always exits along a parallel path. The complete path in the prism can be seen with a 405nm UV laser beam which is made visible via fluorescence of dopant chemicals (such as Pb, Mn, and Zn) often added to create optical glass.
👉 Fresnel Minor Lamp: precision geometry and dichroic glass create an explosion of colors in this incredible creation by artist seanaugustinemarch.
👉 Scale Jupiter and Earth
👉 Scale Saturn with Ring System and Earth
👉 The Planets of Our Solar System to Scale: In this model: Earth (diameter = 0.80 cm) and Jupiter (diameter = 9.0 cm). Wonderful detail allowed by the 3D printing process reproduces the belting on the gas giants. The rings of Saturn are printed on transparency film. Made by artist/maker Jay Fisher using images from NASA.
👉 Kalliroscope with heating element stand: visualizing convection currents. This rheoscopic fluid is special in that the guanine crystals are the same density as the tetrachloroethylene liquid so the crystals never settle to the bottom allowing the fluid to show the slightest movement.
👉 Polaroid Glare Reduction: this retail display illustrates the amazing property of light waves and Polaroid sunglasses. In this Oakley display a white surface is aligned by design so that the light from the white surface is reflected off an image of a surfer such that the glare is so extreme the photo is obscured- however all the glare light can be almost entirely eliminated with a polarizing filter oriented correctly.
👉 Balafire Flicker Bulb: the flexible 15 Watt carbon filament in this bulb oscillates back and forth producing a resemblance to a flame. A magnet, visible as a black rectangle, pushes on the magnetic field produced by the current flow in the filament.
👉 Simple Polariscope: polarized light reveals the hidden rainbows due to internal stresses imposed on polymer materials such as these pieces of polystyrene flatware, a technique used to model stress distribution patterns in engineering.
👉 Newton's Yo-Yo: Newton's 3rd Law states that action force equals opposite reaction force- the the green and yellow spheres have equal mass, so the forces of the collision provide accelerations that are equal and opposite such that the spheres trade places.
👉 Logarithmic Spiral Gears: This set is based on the famous Fibonacci spiral and evokes the cross section of nautilus shell with internal chambers.
👉 Chaotic Pendulum Kinetic Art: the motion of the skateboarder is that of a pendulum influenced by magnets in the skateboard and the mirrored base- chaotic motion is the result.
👉 Iron Filings in Silicone Oil Suspension: visualizing the invisible- the magnetic field lines around a magnet.
👉 Magnetic Field Viewer
👉 Computational Caustic Projection: an image is formed by refraction through a free form lens in a new process that utilizes the physics behind how light is concentrated into caustics.
👉 Acasta Gneiss: This rock is only found in the Northwest Territories of Canada and was collected by Yellowknife resident Mark Brown.

Two immiscible liquids of different densities and beads of two different densities. Shake the bottle to mix the liquids, average density of the mix is less than white beads and greater than blue beads. When the liquids separate, both colours of bead are lighter than the bottom liquid but denser than the top liquid.

Is it density or weight?

[@braeburnhilliard8340]

For the physics quiz, I think there are two types of plastic beads in the jar as well as two types of liquid. Once the beads sink and or float, the liquid then settles to its respective places because one is more dense than the other causing the beads to return to the center dude to the density being different between the two liquids and the two different densities of beads.

[@dibyojyotisinha1426]

The bottle itself says it contains polydensity fluids : ) these two liquids are not so much soluble in each other. So when shaken they form a suspension which is a quite unstable state to be in. The suspension has practically the same density through out. So the difference in the densities of the beads did its job, sending the lighter white beads to the top and the heavier blue beads to the bottom. After a few moments, the suspension dismantles, seperating the two liquids. The white beads are so chosen that it's density is greater than the lighter liquid but heavier than the denser liquid. So it comes down to the interphase of the two liquids. And vice-versa for the blue beads. So, both of them meet eachother to the interphase. I liked the log-algorithmic gears. I wonder where they are used.

[@beaglesguy]

Just found your channel. Love this. I've been fascinated with general physics since I was 10 and learned how to boil water in a paper cup. I've done the surface tension experiment with a tumbler and paperclips. Over 100 before a drop overflow.

[@amichiganboiwhosereallazy1544]

Oh hey that last one I had in my chemistry teachers class last year. There’s water and alcohol so the two different densities make a barrier and the two beads are different enough that they also separate out. Thanks Ms. Rathsack!

[@HuntsvilleSTEAMWorks]

Glad you're still having fun with our spiral gears!

[@peytonjenkins5316]

I know this one! I was thinking about it and here's the science: there are two know kinds of beads with different densities (the blue is greater, the white is less) and clear liquids with different densities too. When you shake, all 4 materials are mixed, and the beads separate first because they are very buoyant and non-buoyant compared to the clear liquid mix. After time, though, the two liquids slowly separate and filter through the layers of beads to the top and bottom of the bottle.

First there were Two bead tribes, The Blue Bison and the White Cranes, living along side the border of their respective Territories. But one day a Catastrophic earth quake mixed them all and they went further inside the territories for survival. As the dust settled and tribesmen returned to their kin, they realised that the territorial border has been left unguarded and the other side can take advantage and capture the fields. So both the sides gathered a militia and charged toward the Border. That;s the untainted truth behind this experiment.

I'm going to guess that the liquid in the bottle comprises two different clear fluids, one more dense than the beads and the other less dense. When the bottle is shaken, the liquids mix and the density of the mixture is between the density of the two types of beads so it goes to the middle. As the liquids separate they move to the top and bottom, based on density, pushing the beads back to the middle.

[@MrJdsenior]

Have not seen the Fresnel lamp, very cool. Answer one: Surface tension brought on by attractive molecular bonding including the obvious asymmetrical geometries involved at the water/air interface. Was I close? ;-) Answer two: This weeks, dissimilar density fully transparent mixing fluids with differing density balls, they move back together at the end as mixing occurs. If not, I'm clueless....great "question", or test. I'm impressed. I especially liked the white straggler that realized late that the inning was over his team was "up to bat". Isn't that "caustic projection" diddlyhooch just pretty much the equivalent of (or analog to) a 2D projected hologram? Yeah and the Sun, also at about 10X diameter of Jupiter (as Jupiter is of Earths), would likely not fit in the room if an eight foot ceiling, and it's a VERY small star compared to some, which VASTLY exceed 10 Sol diameters. Easy to see, then, how the Sun is over 99% of the total solar system mass (I thought it was actually less than this, about 99%). I think the common center of mass for Jupiter and Sol are just inside or just outside Sols surface, not a lot of Sun doppler there to see from elsewhere, especially at Jupiter's "omega". Makes me wonder if the polar scope actually shows any indication of the stresses within the plastic utensils, looking at the patterns wrt shapes. OK, the log spiral gears...awesome. Was trying to think of a practical use for them, nothing so far. You definitely (legitimately, not underhandedly) "click baited" me with that. The dynamic aspect of the filings in silicone fluid...mesmerizing, and instructive, actually. Never thought about what was "ACTUALLY" going on in all the static versions I've seen. Also, the 3D version, knew it obviously, but neat to see. NOW, if you just figure out HOW magnetism works...you'd REALLY have a video. Better yet, how ALL of them (fields) work...UFT. ;-) SERIOUS serious prize worthy stuff. Good stuff, some of the others, too. I'm off to see the wizard...Dorian is on the way...in Orlando. Tornado in Charley brought 30K damage from a falling tree. Hopefully not a repeat, or worse, that one was JUST property damage. This one is starting to look "OFF THE CHARTS"...200 mph gusts....WTH???? Wouldn't even remotely NEED a tornado to drop a tree at those velocities....remember force is the SQUARE of the velocity, so 200 over "just hurricane" winds is like 6X, if I did that right in my head just now.

[@AwesomeStuff91]

They all look so awesome!

[@oka-yoke]

there are two types of liquids in the bottle that cannot mixed like water and oil but totally same color, different density. the plastic densities are close to each other and between those liquids' densities. that liquids cannot be water and alcohol since because alcohol dissolves in water. it maybe gliserin and water

[@pizzasteve5825]

When you shake the bottle the beads get spread therefore the collective volume is less and the mass is the same so because d=m/V the density decreases.

About the poly density puzzle my solution is the the white ones are made from a different material which the mass of them is lower so they can float and for the blue ones the mass is bigger and they go to the bottom of the bottle you can try it with oil the oil goes up and the water down because of the different mass

There are 2 different liquids added, One liquid is more dense than the other. And so are the beads. (For example and visual lessons), Let's say one of the 2 liquids sits at 1 on a number scale from 1-10, and the other at 10. Add the 2 beads that are 2 different densities and place them at 5. And there you have it. The poly density puzzle answer.

[@ammarmufaris6643]

So amazing!

[@streetfood7568]

For the puzzle: there are two clear identical looking liquids in the bottle. The order of densities in the bottle goes, from least dense to most dense, liquid 1, white beads, blue beads, and liquid 2. When you shake the bottle, the 2 liquids are mixed, making a liquid with an in-between density that is more dense than the white beads but less dense than the blue beads, and after a few seconds, the 2 liquids separate, and everything goes back to their original order.

[@darklucifer430]

[@sir_prize_ma_the_farcar4547]

[@linkgamer1233]

the beads are of different density to each other. white is lighter than blue, also the solution they are in when mixed together creates a liquid density that is more than the white beads, but less than blue. as the solution separates, the the denser of the liquids slides under the blue beads (now being more dense) and the other slides over the white beads (now being less dense) together the to liquids cancel out some of their respective densities.

[@ruckenwindgeschichten3099]

The shaking of the bottle adds air-bubbles to it and changes the density. As they leave the water it becomes denser again. Simply hear this effect: Make a cup of "foamy" coffee (it´s called with "crema" I think) Stir the coffee and then knock the bottom of the cup with a spoon from above (so spoon in the coffee) Hear the sound becoming lighter with every knock. Stir it-> dull sound again.

The beads have different specific weights. The blues are lighter than water, the whites are heavier. By shaking the container, the blues are crushed by the weight of the water, the whites flee to the surface of the water! If instead of shaking the bottle were turned upside down, the white ones would sink and the blue would float and so they would stay until they were shaken again

[@CaspaB]

I think the blue beads and the water below were very cold. Hot white beads were added and the bottle carefully topped up with hot water. On shaking, the water temperature quickly equalized to the mid-temperature while the beads were still at their earlier temperatures. Only when the beads acquired the mixed water temperature did they move up/down. I think the beads were soft and had air inside, but also weighted to be the same density as the mixed water. Notice how the background was a neutral color which would hide any condensation on the cold part of the bottle.

[@CaspaB]

Luca's comment sparked another idea. Not air inside, but the beads could be spongy and hold liquid (salty or fresh) until it drained out.

[@eyannnn_l]

This channel is very useful and I'll subscribe

[@ndnofmana521]

When it comes to colors in ink for tattoos each color has a different metal in it. The beads naturally float because buoyant. Therefore the white typically have lead and titanium. Blues typically can have cobalt, copper, ferrocyanide and ferricyanide. The blues are more dense initially but can’t fight the state of its buoyancy is why they sink, then float. The whites buoyancy causes it to float initially but due to the metal in it would cause it to sink eventually (not all the way). Shaking the water causes them to go to their primary buoyancy threshold. That’s my hypothesis anyways. *I didn’t see anything about different liquids in the container so I’ll have to rewatch that.

[@akashgohel5375]

I think there r two liquids of different densities and also both rings have different densities.

[@richardmcginnis5344]

the color added to the blue beads makes them denser and the water in the bottle is sea water or salt water

[@maggpiprime954]

Except, if the blue beads are denser, they would not float back up only to be blocked at the middle by the white beads trying to sink. Right? I do agree there's something simple about the water, salt, as you suggested. Not mixed liquids as some others have. Wouldn't we see the swirls of mineral oil versus water?

[@TheOneShirokage]

Surface tension of the water is to great to break from the top of the cup of water. If beads were continually added after the point where you stopped the surface tension would eventually over come itself and the water would spill out.

[@Jogannez]

different density of beads , and two different dense liquid is used .thats why those beads moves toward mid after sometime

[@juxtapode2781]

for the quizz, i think the blue beads are denser than the whiter. They float inside a combination of two liquids that don't mix very well and tend to separate. When at rest, the beads are in the middle because they sink through the thinner liquid but can't go through the denser one. When the bottle is shaked, the two liquids combine and its buoyancy levels out to make the whites float but not the blue ones, which sorts them out. when the two liquids separate again the whites and blues go back in the middle, with the whites on top and the blues underneath.

[@tomthornton4575]

Ok from the far side, the beads have a different polarity about them, it appears the bottle is plastic, the shaking generates a static electric charge on the bottle, because the beads are polarized, one color will be attracted to the strongest charge, the bottom of the bottle, the other color will want to get as far away from the charge as possible, the top of the bottle where the air gap presents the lowest charge. shake the bottle, the beads separate, as the static charge wears off, the different polarity pulls the beads together. as for why they pull to the center? the beads may have a slight mass difference...? if that were the case, the white beads would hold the blue beads off the bottom, like a sub works. Just a gear-head kind of thought.

[@RayRay-pp2cm]

Wow.

[@haroldhees899]

Two different densities of fluids--one denser than the beads, the other less dense than the beads--and two very different densities of beads. Beads separate quickly because of density differential, and denser fluid then separates and settles through the beads to the bottom.

John Sikes No trolling. I learned about the Fibonacci spiral when I was 11. There was diagram of a sunflower (most common representation ) after seeing that a light bulb went off in my head and I could see that symmetry in everything. I found it captivating and still do to this day. You my friend know your physics from what I can tell. I've only had physics in high school and 3/4 of a semester in college before taking an incomplete due to an exacerbation of previous spinal injury. I struggled with the mathematics but I could still understand the broader concepts . I used to be a voracious reader of many subjects. Having 3-4 books going at the same time. Most of which were of the sciences and spiritulality. I found one complimented the other. As opposed to being mutually exclusive. I studied the mystical teachings of Judaism i.e. Kabbalah and the Zohar was a life changing read. I was warned by a friend who lent me the books that the revelations within the teachings are so profound it can be unsettling. Science is catching up to it. What does this have anything to do with physics? That's up to the understanding of the reader but I do know that it brought the study of sacred geometry to a whole another level. I'm just starved for intellectual discourse. I regret not accepting the invitation to join MENSA at 19 y.o .After my first Stanford Binet and again at 35 y.o. I have to get on Facebook and join a community to interact with. I'm disabled and isolated. There isn't anyone here where I live to interact with on level I desire. I hope you read this without being bored to tears, or just finding it plain laughable. I'm very tired right now. I barely sleep. I've been that way all my life. It's very hard on the body, mind and soul. When I was younger it was much easier to recoup. Now at 55 y.o. not so easy. My mind/brain would be so highly activated it would have to reboot in the way of gran mal seizures. That's the way my neurologist explained it after extensive testing particularly my EEGs and functioning PET scans.BTW I did finish college and received my degree.

[@MrJdsenior]

@@stephenspero3201 NO problem, Stephen. WOW, you've had quite a life. Makes my difficulties (anxiety, severe depression, all deeply and widely family genetic) sound benign. I found your story quite interesting, and a little bit unsettling. I'm not religious anymore, but I almost want to pray for you, anyway, just in the off chance. ;-) I do agree that philosophy and science (and some theology, for instance some of the Buddhist thinking, the more scientific parts, on mind/body especially) are kind of coming around to each other, and much of this has been rigorously experimentally researched and proven (they are the "happiest" people on Earth, and have very high control of their bodies, at least within their highest echelon according to brain activity scans). I still think living life the way Jesus taught (love, non-judgement, etc) is the most intelligent and socially beneficial mode (he was BRILLIANT, even if not GOD IMHO). I readily admit I'm not too knowledgeable on Buddhism, just what I've read, and the parts that got incorporated into Christianity. I claim fairly decent knowledge about Christianity, (as I was an active believer for most of my life), but know next to zip about all the others, and am no longer interested in pursuing the "supernatural". To each their own, I say, 'til they start trying to convert me, then "Katie bar the door", they are in for some SERIOUS no holds barred discussion, (especially after they enter the "I'm going to kill you" mode, which is comment in comment sections. Very Christian, that, don't remember reading Jesus saying ANYWHERE he wished us to live like THAT. If only more "saved" Christians ACTED like they were saved, right?...though I knew many, also, that did, walked the walk, so to speak; loving, generous, always looking for the good in people and life). Supporting most supernatural "claims" is really difficult, actually next to impossible from a logical standpoint. No data, just words in books from LONG ago, you either believe it, or you don't, so arguing from either side is really kind of pointless, unless you find someone extremely knowledgeable that has INTERESTING views on one and is willing to discuss things rationally and with mutual respect, RARE, but occasionally... ;-). And yeah, I'm 60 so I get the "old man" stuff, that one happens to ALL of us, unlike most of the rest of what you've been through, which, thank god, happens to almost none of us. Shame it happened to you. Life is hard enough without all that going on. Makes it about 1000 X harder, I'm quite sure. As for math difficulty, I had college math up through differential equations during my engineering schooling, and I not only missed the Fibonacci/Golden Mean relationship, but QUESTIONED it AFTER you pointed it out. Kudos, man. As for math, you are not even REMOTELY the only one that has/had trouble with math at higher levels, and it gets more difficult and "weird" (at least for me), or less intuitive on some of the higher levels (statistics sometimes got TOTALLY unintuitive, generating answers you'd SWEAR cannot be "right", but when you checked them, they were). I actually only knew a only a few that struggled with math not at all, and one of them became a math major and prof, and then wrote an awesome investment program while working for the goons on Wall Street that has made him (and them, probably) VERY rich. The other placed very highly in Math Counts as a kid, an international competition, and went on to work at Microsoft as a programmer with his Computer Science degree (with probably some extra math, don't know, should ask). He was one of my kids best friends when we (and his parents) homeschooled our kids, partially in the same support group. He set the curve in his calculus classes in college at a MUCH younger age than all of his classmates, doing "high school" at home and very early college enrollment at the same time. He was lucky that he was well on the way to his current 6'4" stature then, and looked older, or he probably would have received even more grief for it (per his own words, "I'm not going to tell them"). I worked at Martin with his dad, and he was a super bright guy, too, one of our top digital design guys (my dept.), did GAPP ASICS and the like, the REALLY tough, very involved stuff that economically was required to be right in VERY few iterations. I hope your problems diminish, you really sound like you deserve MUCH better. Oh, and in the comments, if you do read them more extensively you will find very interesting stuff and cogent comments, which ours, the latest two or three of them anyway, we are in agreement, are not at least, cogent to the video. But that's OK in my book, and that's the ONLY one that matters (kidding). You will also find the "bottom of the barrel" idiots trying to promote stupid crap like "flat Earth", "Rockets don't work in space", (They definitely do, I've designed for one such program) and Moon hoax (thinking we didn't go there)...just plain moronic. Comments contain the entire spectrum of the "doers and thinkers" to the Dunning Kruger poster boys and girls. For you, I suspect, telling the difference will be "child's play" (it seems to be mostly the low end). Cheers, and I hope things improve. You could still join MENSA, though my wife and I never did, didn't sound that interesting then, might be more now, but not really my cup of tea.

The density of the beads causes them to react like that

[@sudiptamukherjee6701]

Solution: The bottle contains four components; two liquids of unequal densities, and two types of beads of different densities. After shaking, the white beads, with their lighter density gather on top and the blue beads, being denser, gather bottom. The white beads being denser than the upper fluid comes down while the blue beads being less denser than the lower fluid floats up. For easiness : order of density- Upper fluid< white beads

"Wow!"

science is so AWESOME

[@physicsfun]

Yes!

Great video

WOW!

[@brainlesscratchandotherstuff]

when you are showing off the simple polariscope im wondering why the prongs are so short on the fork

[@prajwalacharya2656]

Density awesome bro

[@MegaGaming11]

I really hope no one was completely dense about this? obviously it's got to do with the blue beads density being higher than the white beads when disturbed but lower than waters when still for thirty seconds or more. Vice versa for the white beads.
