Were the slo mo guys we have been for many years now.

We're in a quarry today, not in my back garden, because this is gonna go up really high, and we don't know where it will land.

Yeah, exactly what we're doing down is a classic physics experiment where you take some of the coke out there and replace it with liquid butane fuel.

It shoots off like a rocket because of physics because of physics.

There's a pretty cool science experiment using the interesting properties of butane because it is boiling.

Temperature is about zero degrees C, which, if you're American, I guess, is something thirtysomething Fahrenheit.

It's basically when water freezes 32 for two for tonight.

It's stored as a liquid inside this cannon because it's such a it's only zero degrees.

It means it's not super high pressure in there.

What's happening is gas will come out initially liquid, but it's just gas.

Letting the gas escape is if I turn it down like this like when you're feeling a lighter and you're actually using the fuel.

We're gonna use that for we're going to use that inside of this coat bowl.

Now, I'm gonna pour some of this coke out, probably down to like, here ish.

And when I put the liquid in because the butane is less dense than the Coca Cola, it will sit on top and a little layer like that, and it would start boiling then and vapor will come out the top.

But when I turned upside down, what happens is because the butane is pretty much immediately boils because got all the contact with the coat, which is warmer than the butane, and cause it to instantly vaporize, which increases the pressure inside the coat can, causing a rapid expansion of gas and then escapes out the bottom causing a sort of rocket effect on this Venturi shape here, where increases the pressure due to the narrowness of the bottom of a but also helped with that.

The effects aren't is pronounced because of this.

But with the Coca Cola, what happens is the combination comes out of solution, and that increases the amount of gas in the bottle even more so you get even more of a rocket effect, we will begin 1000 frames a second info.

Even though this is a interesting science experiment, definitely.

The bottle could fly up and hit you in the teeth, all the eyes, and it's also incredibly flammable.

That was like it was struggling up first.

So it's all about rapidly turning over rather than, like, slowly, because it has to right through the coat.

Yeah, so let go at this point is expected it to go.

And I think it's just grabbing kicking in?

Until then, it's like way butane coming up.

Like some sort of muppet, You know, one of the Three Stooges.

So it looks like what actually happened was the Kogel left the bottle pretty much, and then it went off, I think.

I want to see with the feds if I tried to track it.

There's no way I'm gonna be able to do that because it doesn't take off immediately either.

Actually, we should take measurements of the size of the coat bowl, and then we can park how quickly that's moving.
