Experiment with projectile motion with this simple device! The spring-loaded 16" launcher will send soft foam balls flying up to 20 feet. It includes twelve 1" diameter soft foam balls. Young kids will enjoy just launching the balls and trying to hit targets. Older kids can actually use it for motion experiments with a little research. For example, you can use it with a stopwatch to determine velocity or experiment with a protractor and stopwatch to determine how range and velocity vary with launch angle.
