I3-12. Water Barometer - Can Crusher
To illustrate a result of atmospheric pressure.
Rectangular can with special cap and 15 feet of thick-walled rubber hose, large plastic
Requires a high ceiling!
A rectangular can, connected to a long rubber hose, is filled with water from a large
reservoir. The can is then raised about 15 feet, keeping the end of the hose in the
water reservoir. The pressure differential between the inside and the outside of the
can crushes the can as the water runs out in about 30 seconds.
