Crushing cans with your bare hands or stepping on them with your full body weight or shooting them with a bb gun are all fun ways to destroy an aluminum can. What might be most fun is letting it crush itself. How? Magical pressure.
It's the water, friends. Grant Thompson shows us how to do it. Just heat up an ounce of water inside an empty soda can until it's steaming and then place it upside down into a tub of ice water and watch it collapse. It's because the steam cools down so fast it creates a vacuum that crushes the can. Science experiments are so fun.
