How Water Guns Work

Have you ever wondered how a Supersoaker works?

Over the summer I built one in a summer engineering camp called TARGET (The Academy at Rutgers for Girls in Engineering and Technology).

Thesuper soaker consists of two one way valves, a nozzle, and a pump. When you pump the water it goes through the first one way valve and creates pressure in the storage container. This builds up so that you can spray at large distances. To spray you have to close the first valve and open the second valve. This releases the water which shoots out because of the pressure. The picture is a simple diagram of a prototype Supersoaker.



Materials:
7 feet of PVC piping
2 one way valves
1 funnel
1 cap
water sealant glue
clear plastic tubing
1 elbow connecter
2 Y-connecters
1 dowel
2 rubber rings

you also need power tools to make the nozzles out of the caps
and a PVC cutter
