So explore projectile motion with this 100% safe, chemical-free air-powered projectile. Accurate and repeatable to an amazing degree Projectile Launch Pad Seller! BEST Thanks to the hard-plastic chassis, this missile flies straight and true with minimal wind effect. Since it takes off at the same velocity every time, your outcome is always precise and consistent — important for students testing predictions, who’ll reap rewarding results. And it’s a breeze to use. All you do is pressurize the launch chamber with an ordinary bicycle pump. When the pressure is high enough to pop off the thrust washer, the projectile blasts into the sky. Each projectile comes with four different thrust washers — Low, Medium, High, Super — so you can vary launch speed for different experiments. You can even build a launch pad (or use the one to the right) to vary launch angles. Then your students can use Newton’s Laws to predict where the projectile will land! For Air Powered Projectile Lab Software, see Interactive Physics on page 31 This easy-to-use launch pad utilizes six wedges (sold separately) that let you vary the launch angle from 30˚ to 55˚ (in increments of 5˚) so you can explore different aspects of projectile motion and Newton’s Laws. Comes unassembled. Achieve repeatable and predictable results! Heavy-duty Air Pump! NEW & Improved Design! Set of 6 wedges to vary launch angles and set of 4 washers to vary launch speed.
