What could be more fun than instantly crushing a can while demonstrating the amazing power of science!
In full disclosure, this is a trick I learned from my dad, Jetpack Prime, who long ago "went pro" with his Instructables in that he is a physics professor (a really good one).
This is also my first instructable with my nephew, Jetpack6, as cameraman.
Warning! This instructable involves hot thigns such as heated metal and boiling water. Be very careful!
Step 1: The Set-Up
You will also need a stove, fire, or hot plate and a container of room-temperature water. A healthy curiosity and adventureous personality is always helpful.
Fill the first half of an inch to an inch of your bottle with water.
For the platic bottle I suggest indirectly heating it. To do that, immerse the bottom of the bottle in a pot of boiling water until the water in the bottle boils. Do not leave on the cap!
Do not let all of your water boil off!
