As the water temperature rises, the can will fill with water vapor and steam will escape from the can's opening. 4. USE the tongs to quickly PLACE the can, open end first (upside down), into the shallow pan filled with cool water. Quickly, the can will be crushed, and will give off a dull "pop" sound. What's happening The air pressure decreases as the water vapor condenses inside the can. The can is crushed because the air pressure inside the can is less than the air pressure outside the can.

How powerful is air pressure? Can it crush a can? Conduct the experiment below to find out.
Materials
hot plate empty soft drink can tongs to pick up a hot soft drink can shallow pan filled with cool water
Instructions
1. This experiment can get messy, so get a parent or adult to help you! 2. PLACE a spoonful of water into the can. 3. PLACE the can open side up onto a heated hotplate. As the water temperature rises, the can will
fill with water vapor and steam will escape from the can's opening. 4. USE the tongs to quickly PLACE the can, open end first (upside down), into the shallow pan filled
with cool water. Quickly, the can will be crushed, and will give off a dull "pop" sound.
What's happening
The air pressure decreases as the water vapor condenses inside the can. The can is crushed because the air pressure inside the can is less than the air pressure outside the can.
