Teams of high school students use their understanding of projectile physics and fluid dynamics to calculate the water pressure in squirt guns by measuring the range of the water jets. They create graphs to analyze how the predicted pressure relates to the number of times they pump the water gun before shooting.

In this service-learning activity, teams of students in grades 10-12 learn the basic principles of fluid dynamics by designing and testing a prototype system to pipe water from a storage tank to a Tippy Tap hand-washing station similar to inexpensive homemade devices used extensively in the developing world.
