Super Can Crusher

Question: What will happen to a steaming hot soda can when placed in ice water?

Hypothesis: When a steaming hot soda can is placed in ice water we think it will immediately be crushed because of the change of air pressure from hot to cold.

Materials : 
1. tongs 
2. hot plate or stove 
3.water 
4.empty soda can 
5.tray filled with ice water

Procedure

Safety Procedures


 1: Keep fingers away from the sharp soda can.               2: Don't touch hot plate or stove.
  3: Don't place fingers in boiling water.                     
   4: Use tongs or an oven mitt to handle steaming soda can.

1.Take a shallow tray and put enough ice to cover it's base. Then pour in water to cover the ice.

2.Next put a small amount of water into an empty soda can. Then ask an adult to place the can on the hot plate or stove until the water boils and you see steam

3.After that turn the heat off. Ask an adult to pick up the can using tongs, as quickly as possible. place the can upside down in the tray so that the whole thing is under water.

4. Finally after a moment or two, the can will suddenly collapse as if it was crushed by an individual hand.



Special Needs:
1. Hot plate or stove 
2. Oven mitt

The Science behind it:

Cooling air can change it's pressure and have dramatic effects. Lowering the pressure inside a can leaves it unable to withstand the pressure of the air outside it, so it is crushed as if by magic.

James and Robert

Robert and I are great friends, we met because we were in the same class. We both enjoy playing basketball and other sports. Robert and I are partners in science night because I needed a partner and after that Robert said yes and thought it would be really cool.
