Spring-Loaded Projectile Launcher, 10ft Range

This spring-loaded projectile launcher has a range of up to 10 feet and is constructed from heavy-gauge steel for long-lasting durability. It features a string release trigger mechanism with two bore sights and fires a 19mm diameter ball with a fixed launch position that minimizes spin, producing trajectory variations of less than 1cm. The launcher pivots from horizontal to 90 degrees, with a 1-degree increment protractor and plumb bob to indicate the desired launch angle. A clamp is included for securing the launcher to a table or countertop edge. The kit includes the assembled launcher, two aluminum balls, a protractor, a plumb bob, and an experiment guide covering kinematics, muzzle velocity, and optimal launch angle.
