Can Crushing Kitchen Science

I did this in my Phys Science class last year lol

blink blink blink blink blink blink blink. but really nice experiment!!!!!! I always like to see a father and son doing a project together

A classic experiment (I think versions have been posted here before).

Slight correction to the explanation - you didn't just heat the air in the can, you displaced it. The steam from the boiling water replaced the air. When you cooled the can, the vapour condensed, decreasing in volume dramatically, creating a vacuum.

You don't need the ice for it to work, cold tap-water is fine, and if you use deeper water, you sometimes get a satisfying smack sound as the water rushes in and hits the inside surface of the can.

It's good to see a Dad and Son doin' some science together!
