Precisely launch 16-mm steel balls at 3 spring settings and at a range of launch (elevation) angles. The built-in protractor and plumb line make it easy to set the launch angle to study projectile motion with ranges of 1 m, 1.5 m, and 2 m. A magnetic piston prevents the ball from touching the sides of the barrel, ensuring a straight launch every time. The result is precise, repeatable projectile motion experiments for fun classroom demonstrations.

The Mini Projectile Launcher lets you precisely launch 16-mm steel balls at 3 spring settings and at a range of launch (elevation) angles, from -45° (downward) to 90° (vertical). The built-in protractor and plumb line make it easy to set the launch angle to study projectile motion with ranges of 1 m, 1.5 m, and 2 m. A magnetic piston prevents the ball from touching the sides of the barrel, ensuring a straight launch every time. The cable release smoothly triggers the launch, to prevent jerking. The result is precise, repeatable projectile motion experiments for fun classroom demonstrations. Perform classic experiments comparing calculations with experiments such as measuring range versus angle, determining whether the ball scales a wall or lands into a can—all while studying conservation of energy in general. The launcher can stand on its own or may be clamped to a bench (C clamp not included).
