Supplies Needed:

Coffee Can with Lid

Water

Nail

Hammer

#1: Place 3 small holes in the bottom of the coffee can using the nail and hammer

#2: Place 1 small hold in the plastic lid

#3: Fill the coffee can about ½ full of water and place the lid back on.

#4: Press down on the lid while your finger is over the hole on the lid. A stream of water will flow out the bottom holes of the coffee can because of the pressure on the lid

#5: Slowly stop applying pressure to the lid. Watch as the stream of water stops coming out the bottom of the coffee can. You are able to stop and start the flow of water by placing and removing your hand from the lid because of pressure!
