careful about copper poisoning

Wow so can’t you have a cube of gelatin or crystal and it’ll show you a 3D version of what’s in the drop?

Thanks u really helped a lot

fail. he saw the ears are 2d flat.

you are so underrated man

I first noticed the noise when I was a kid. I melted a GI Joe figures head over the edge of my porch and it made almost a buzzing sound.

Love this

Great video!

Fabulous! Could you please tell me where to get a xenon globe.

reminds me of a video the guy said a candlestick contains the same amount of energy as a stick of dynamite. That was really cool to contemplate, and a great way to exercise the mind on spatial awareness of time and energy

As a former lifeguard and now I teach chemistry and physics at both the high school and local colleges, you’ve got an awesome “Wizard in Training”. Keep up the great work!

I really really dont understand how this channel dint get mega big. Its awesome

Yeah the best video

old man✅ making science ✅ and fire ✅ and it's green✅✅✅

I’m a 65 year old Electronics Technologist, born with an inquisitive mind. I must say, Kudos to you and your young scientists. Such an interesting, inspirational and informative little video! All children interested in science should see this simple, yet very effective demonstration! I recall many years ago we studied the principles of pressure in our high school physics classes, but it’s always nice to see a little “refresher” like this. You guys need to be on Television! 😊

This experiment is a classic! My middle school chemistry teacher did a very similar one. Ever since I've always loved learning about chemistry. I guess you could say it really SPARKED my interest.

Cooo science going on there 😎

Very cool video

had no idea this was possible - how cool!

Works great with milk jugs to.. I think it's the boiling of the plastic and the bubbles can't form so I think it's like the doplor effect or what ever it's called when sound waves stack like in nascar... but I don't know what I'm talking about I had a hard time in high-school

I have wait until the end of the video to hear what i was thinking were to be the cherry in the pudding, and it was not 😅 : the crystals are pure iodine anew !

Criminal this channel doesn't get more views. Try throwing some big red arrows in your thumbnails to get clicks lmao. Maybe you could even do a science video on why red arrows make people click lol.

@KazmirRunik and @bakersbread104 have made good answers, but I think I will explain it in my own words. So essentially the cause of the sound comes from the flame on the droplets of plastic. as it falls, the flame will burn toward one side, then as it continues to fall, this is reversed and the flame migrates over to the other side of the drop of plastic, and this happens many times each second, creating a pulsing sound as the flame moves from one side to the other. simultaneously the flame will also increases and decreases in intensity as the escaping gas gets opportunities to burn in one of the vortices, or gets mostly blown out by the fast moving gas on the edge. the reason why it does this is somewhat complicated, and involves fluid dynamics. Its called vortex shedding, and is common when a fluid or gas flows around a rounded object such as a ball, cylinder, or even a droplet of molten plastic. the heat and gas released by the flame only increase this effect by both disturbing the airflow around the droplet, which encourages the unstable wobble to start, and also making each vortex much louder (audible as opposed to inaudible) by creating brief instances of faster combustion as each vortex passes by the flame. when there is a repeated pulsing in the air, we can hear it as sound. and that is why it makes the sound it does. This is actually visible on-camera if you watch the video during the close up shots. you can see the flame wobbling from side to side, and flickering in intensity. 8:04

How has this not more likes? Like, I know all this stuff and have seen it before many times but this is way more educational and entertaining then other examples!

The path of energy goes all the way back to before the "big bang" if you really wanna take the time to figure it out 😆

1:08 It's not "Iodine powder dissolved in aclohol" It's usually povidone (aka Polyvinylpyrrolidone, aka PVP), which is a polymer, dissolved in a solvent like water (but often also alcohols like ethanol, isopropanol, glycerol or PEG), the former forming a triiodide complex. The iodine is already partially ionized, which is how it can form the triiodide species (being brown colored) with elemental iodine (being purple) and be stable and applicable for disinfection. Like, c'mon guys, ya'll are supposed to educate here, so at least be accurate, which is literally what science is all about. 5:06 Melting is less of a problem, but it could crack. Leaving shards while you're panicking. Accurate danger assessment is important. 10:46 "evaporate" after using "sublimate" multiple times and got missed by post production lmao

are Air fresheners an example of sublimation?

Aren't iodine crystals explosive?

hahaha fuck

Amazing and pretty

Crystals are cool

chaotic alternation between static and sliding friction is also the generation of string vibration in bowed instruments

Where can one get mercuric oxide?

Does it work with any wood?

Similar to my gasification wood burning stove, I think.

2:06 let's try it out DIAGONALEY!!!!🫨

These kid don't fully realise how lucky they are to have this person in their life. Thank you for sharing.

"drippage and burning" is maybe not a good thing to overhear at the Dr's office

Surface area, fibers burn faster and more aggressively, it’s similar to stick gunpowder vs ball gunpowder.

Paper doesn't ignite at Fahrenheit 451.

Gasohol

very informative

Amazing

Waao incredible 👏

Very cool demonstration! Love the "fire and drippage" comment LOL! A long time ago they used "producer gas" to power gas lighting and engines in industry. The "Gas producer" was similar to what you have done there.

Almost reminds me of Mr. Wizard. Nice to see people teaching science in a way people can be interested in at a young age.

45yr old man and this just became my science class 26yrs post high school. ❤

That torch/lamp gadget seems pretty handy. Glass retort is good for demonstrations, though practical pyrolyses are of course performed in a semisealed tin can, steel tank or a barrel. Advanced decompositions are often catalytic and run in a special hydrothermal or pyrolytic reactor.

We used to braid hefty bags and light 'em up. The higher up you can get for the drop the better. Fun trip toy but profoundly toxic😂❤🎉 Zzzzzzzt zzzzzzzzt zzzzzzzzt

I will unfortunately be trying these at home.
