As an astronaut, Chris Hadfield knows more about physics than just about anyone you know. So when even he’s amazed by a phenomenon like this, you know it’s got to be pretty mind blowing.

For this experiment, Chris is actually inside a facility on the ocean floor, where the effects of pressurization create some pretty weird conditions. Just watch what happens when he tries to open a soda can after shaking it!

Ha! That really had me going. Still, it’s actually pretty cool to see how just a slight difference to our conditions can change everything!
