[@ElkHunter111]

I'm certain it wouldn't work, but what would happen if you placed two siphons leading into two bottles in such a way that they feed the liquid into each other? I'm curious as to why that wouldn't make perpetual energy.

[@tonedmagician7627]

You would need to have one bottle higher than the other and so the water would only flow one way. Good question though :D

[@Reach3DPrinters]

Hey Zack, So energy is only transferred from a position with potential, relative to another position. Ben is saying that if the bottles were at the same height, they wouldn't have a potential difference in gravitational energy. The idea of a perpetual energy device is interesting, but you cant get something from nothing.... The best we have come up with is taking unstable matter, and smashing it with particles, breaking it apart, and some of the most unstable leftovers turn directly into energy. This process is called nuclear fission. There is enough energy bound up in the atoms of a sheet of paper, to run an entire city for a few days!!! The problem is... the atoms are VERY stable in paper, and to convert them into energy requires a massive amount of energy, and the reward is not very great when you consider the costs of building and operating the machine. So we use unstable atoms,... which by nature, are unstable and rare, such as Uranium 238 which is just the beginning of a long process requiring U235 to convert U238 into Plutonium 239 for chain reaction.... all this just to create heat to run steam engines, ie Nuclear power plant. Mechanical energy devices also have great loss from friction, such as bearings heating up. Be it mechanical friction or wind resistance. You also get loss from inductive forces (magnetic fields)... So when you wave a magnet across a coil, and there is a load across the coil (like a motor hooked to coil), you will get a magnetic field resisting the motion of the magnet you are waving over the coil. That is basically a generator, and the greater the load on the generator, the harder you must work to swipe the magnets over the coil. You an drop a neodymium magnet down a thick copper pipe and watch as the magnet slows down, almost hovering down the pipe. The field of the magnet is being inverted against the magnet, from the closed loop of pipe, and creates an opposite field, causing the magnet to hover, but slowly fall, as energy is lost to heat and other fields nearby. This is lenz law. Bottom line, you cant get something from nothing, only transfer... and in every transfer, there is some loss of energy... so best to find a lot of energy, and try to find a way to harness some of it. Our best source is probably nuclear, geothermal, tidal, wind or solar. Note: Geothermal is heat from molten rock in the earth. Tidal is gravitational energy from the moon, tugging on the ocean. Wind is basically solar energy from the sun heating the surface of the earth. Solar is directly from sun. Nuclear... well, that is beyond me, exactly the properties that formed the atomic and subatomic bonds in a supernova. If your interested in how energy changes states, look into the Feynman diagrams, how subatomic particles change states. It deals with wave in the electromagnetic field and how different wave forms coalesce and disseminate with/from each other. A lot of this goes into the model theory of quantum electro dynamics... which seems to best fit... ripples in a field... what is that field... hmmm loops, strings, aether... All we know is it is directly relates to the effect of gravity.

[@AndyLundell]

As was mentioned, it wouldn't work because the water in a siphon will only flow from high pressure to low pressure. But it's not a stupid question. Before the mathematics of this sort of thing were worked out, a number of perpetual siphons were seriously proposed as perpetual energy sources. A fun point : Some of them actually work if you use Coca-Cola instead of water, because Coke makes its own pressure. ... until it goes flat, anyway.

[@pkillor]

Very illustrative... It occurs to me that using this same effect, you could model the operation of a logic gate, we change the electric fluid for an aqueous fluid... It would be a VISUALLY ATTRACTIVE WAY OF SEEING HOW MICROCHIPS WORK

[@uptbug]

Get this man a TV show! Mr. Wizard 2019!

[@Graeme_Lastname]

Simple and well presented. The world needs more like this. In the one with test tube and straw, I'm wondering what is the cause of the water inside the tube being higher than level in the main container before the siphon had started. I've got my ideas but I'd like to get your thoughts.

But why doesn't the liquid stop flowing once the surface level goes below the point of drainage?

[@The_Forge_Master]

Air can’t get into the tube to bring the inner water level down until the surface level gets below the outer tube.

[@alphamoonman]

@@The_Forge_Master But at some point the pressure of the water level outside the tube is what causes it to flow. But what is keeping that pressure on as the liquid gets below the required level?

[@aboudimassoudi7817]

Love you sir More explanation won't be bad

[@Tom_Tom_Klondike]

Keep it up Bruce! Another great video!

[@littlebear7523]

if you used a liquid with a higher boiling temperature, could you siphon higher?

[@carultch]

Not very much, because under most circumstances, it can't go lower than a perfect vacuum. 10.3 meters is the theoretical height for sucking water up a tube, assuming you can get it as low as a perfect vacuum. It requires a liquid with less density for atmospheric pressure to be able to lift it higher. So if you used alcohol instead of water, it could go higher. While if you use a dense liquid like mercury, it will only rise 76 cm under 1 atmosphere of pressure, which is why we also call 1 atmosphere as 760 millimeters of mercury, based on the working principles of the mercury barometer.

Hi Bruce Nice experiments, Id like you to experiment with another water antiintuitive water behavior... it is very easy, it consists of a water tank small or very big like used here in Argentina on top of houses,,.make a small one say one meter high with plastic bottle.. the just put a hose down from the very bottom ( not siphon). like 1/2 inch and 2 meters long, if you put the EMPTY hose straight down the water will run freely, but if you for example put some midle part flat horizontally, some water will reach the end ( you had it closed first) and some air will be in the midle of the hose, then you open the end and the air inside will try to float up stream, wile the water would try to go down, sometimes the air buble gets in equilibrium and the water would NOT run even if the end is lower and fully open.. this is a comon problem for house water piping even if the water tank is over 10 meters and the 3/4 inch tubing goes straight down, there are interestig factors involving tube diameter, size of the air buble, pressure andn so on ... congratulations for your teaching vocation!!!

I have a question regarding pet water feeders, how does the water reservoir that has a higher level, not fill the lower bowl and overflow it ? Great channel Bruce.

[@YeanyScience]

you can do the same thing with a glass full of water, upside down in a bowl of water, water can't flow out of the dispenser or the cup example unless air can get inside the container to replace the water coming out. When your pet drinks, the water level drop in bowl far enough that the mouth of the water container is clear of the water level and air can get into container. Water flows out until the level in the bowl rises enough to seal the opening of the water container again

[@pavellambracht5823]

wait, so you do not have to do any additional manipulations with a tube, just insert it into two containers one filled with any liquid and elevated higher than another or you have to suck the air out from the tube?

The theoretical limit for how high you can suck water up a tube, is around 35 feet, given a 1 atmosphere environment on the source container. It would be an interesting trial to this experiment to see an attempt at siphoning water higher than 35 feet above the upper container.

[@YeanyScience]

We did the sucking through a straw experiment a few times with students until I heard it can be harmful to the lungs, same with exhaling as hard as you can. Not sure about the accuracy of either statement.

[@Resonanttheme]

I was toying with some glass capillary tubing close to the 800 microns mentioned in this Scientific American article and wondered how much it assists in allowing water to be raised up a tree. The water climbed about 2 centimeters and coupled with the affinity water has for the cellulose walls of the vessels and tracheids, adhesion and cohesion forces combined, how those qualities go above the typical height you can raise water before it "breaks" or cavitates. The smallest diameter mentioned was 20 microns, even less that a thousandth of an inch. Anyway maybe a more narrow tubing would be less likely to break a water column if going for more than the standard height water can be raised before collapsing or buy you more time before it does, if metastable occurrences are possible or can be brought about with relatively wide diameter tubing, that is compared with the tiny stuff trees use. How do large trees, such as redwoods, get water from their roots to the leaves? "Theoretically, this cohesion is estimated to be as much as 15,000 atmospheres (atm). Experimentally, though, it appears to be much less at only 25 to 30 atm. Assuming atmospheric pressure at ground level, nine atm is more than enough to "hang" a water column in a narrow tube (tracheids or vessels) from the top of a 100 meter tree. But a greater force is needed to overcome the resistance to flow and the resistance to uptake by the roots. Even so, many researchers have demonstrated that the cohesive force of water is more than sufficient to do so, especially when it is aided by the capillary action within tracheids and vessels." www.scientificamerican.com/article/how-do-large-trees-such-a/ Tidbit The increase in transpiration is due to the increase in temperature - water molecules have adhesion with the walls of the xylem - This results in tension as water is pulled up the stem - An increase in the flow rate will cause an increase in tension and cause the walls to be pulled inwards The diameter of a tree trunk reaches its minimum when the flow rate in the xylem is at its highest at midday. quizlet.com/119195082/flashcards
