Introduction: Collapsing Can Experiment

About: I am just a person who loves doing crazy and fun things... I always love to try to innovate when I can, and share any new discoveries I find... That is why I have recently started recording my shenanigans s…

Hello YouTubers, and Instructaganders It is of course I TrollFaceTheMan Here!

And today I am going to Show you how to Decimate a Can through Spontaneous Contraction of Energetic Gaseous Molecules, Causing an Isolated Vacuum in a Container, and Thereby allowing Atmosphere Pressure to Crush it. This is called the Collapsing Can Experiment.

As complicated as it might sound, it is honestly fairly simple. The only things we are going to need is:

A. Some Aluminium Cans, Non-Returnable Ones are Ideal. But if you don't have any cans Laying around like me, you can Just typically walk right down the Edge of the road, and find some laying in ditches. A sad truth, but at least you can do the experiment and clean up some liter at the same time.

B. Some kitchen tongs, or just something in general you can use to get a good grip on the can. You defiantly want something Fire proof though.

C. A decent flame Source, I am going to be use my Kitchen's gas Stove.

D. And lastly Just a simple Bowl of water, the colder the better.

Alright, so what is our goal here..? Well what we are doing is heating the can, and thereby heating the Air inside of it, when Gas Molecules are heated up they excite, which causes the Molecules to move faster, this inadvertently increases the amount of times, and force in which the Molecules bump into one another. Along with everything else. This is what we Know as Pressure.

That is why something like a can of aerosol, is so dangerous to leave in a place of intense heat. The heat causes the Molecules in the can to excite and the Pressure Increases, this gives the Illusion that the Molecules are taking up more space, in reality they are exactly the same size, but instead of growing their bashing into one another way more often, this constant force involved creates pressure which continuously pushes outward. More Heat, Faster The Molecules Move, More they Bump Into One Another along with Everything else. And the More pressure that is generated.

So what we are doing in heating the can, is inadvertently heating the Air inside of it, causing it to expand. But because the top of the can is Open, the heated air can escape allowing for the equalizing of pressure inside the can with the outside atmosphere.

Now what I am going to do, is quickly Flip the can Over Open-Side-Down, and Plunge it into some cold water. The results are quite Drastic. What happened..?

Well like I said, as we heated the air the Molecules Excited which generated Pressure, but because the can was open it allowed for the Pressure to escape which meant a lot of excited Molecules Floated right on out of the can. Which meant at that point, the can had significantly Less Gaseous Molecules in it Per Square or Cubic Inch, then the outside Atmosphere.

When we flipped over the can into the cold water, we suddenly stripped the Gaseous Molecules of a lot of their energy. That energy was in the form of heat that the water absorbed. When the water absorbed that heat, it caused the molecules to Suddenly slow.

In doing so, the gas inside the can Violently contracted meaning the can formed a vacuum inside of it, and because of this In-equalization of pressure the Outside atmosphere is able to press down in order to try and equalize the cans internal pressure, this inadvertently crushes it.

Now technically speaking the air doesn't have to crush the can in order to equalize the pressure, the water we dip the can opening into very much could be sucked up into the can to Balance the Pressure, and it does somewhat. But the water isn't able to move quickly enough to fill the sudden void the gas leaves, that's why the can gets crushed in stead of just sucking up the water.

So now that I have explained why it has happened, let me explain how you can do it. Now I honestly thought when I had did this as a kid that I came up with it. Didn't take long for me to realize that actually this is a fairly common science demonstration, and as such many people have different ways of doing it. I'll leave a link in the Description below for how you can do this experiment by boiling some water in the can instead. That way is probably better for smaller flame sources like Candles.

But the way I'm going to demonstrate this one is using my original technique I did as a kid. So just take you can and hold it over your flame, in my case of course it's a stove-top. Try and heat the cans outside, this take some rotation but it isn't overly complicated to do, you'll want to do this for around 40 Seconds.

Remember were trying to heat up the air inside the can, so more even heating helps to make sure we're not heating the Air up to have it immediately cool of if it touches some part of the can that was not heated.

Now at some point before you're ready to dip the can, make sure you hold the flame right in the Cans Opening for around 10 seconds, just to make sure the air inside is thoroughly heated, if you don't take this extra step, your demonstration might end up looking like this instead...

So now that has been done, quickly take your can and plunge it Opening down in cold water, and you should see it crushed by an invisible force right before your eyes.

Yikes crazy to think, the same pressure is bearing down on you this very moment. Good thing our bodies are equalized, otherwise the average person would be crushed by over a tonne of Atmospheric Pressure.

So now for fun, let's do it one more time.

Remember this is a fun demonstration to impress your friends and family with, just make sure you do it safely.
