A Complete Classroom Set of our popular Air Powered Projectiles  Enough for 6 lab Groups!
Accurate and repeatable to an amazing degree, thanks to the hardplastic 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, and Super  so you can vary launch speed for different experiments. You can even build a launchpad (or use the one below) to vary launch angles. Then your students can use Newton's Laws to predict where the projectile will land!
Projectile LaunchPad
This easytouse launchpad 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.

Here's a lesson you can try with the airpowered projectile:
 Shoot the projectile straight into the air and measure how long it takes to land. (In this example, let's use 6 seconds).
 Divide that time by 2 to get the time it took the projectile to reach maximum height and slow to a stop (3 seconds).
 If gravity slows objects at a rate of 10 m/s per second and it took the projectiles 3 seconds to slow to a stop, it must have started at 30 m/s!
 Now assign an angle, say 60°. The initial velocity stays the same, so we can use trigonometry to find the x & y components.
Vy = 30 m/s (sin 60°) = 26 m/s vertical velocity
Vx = 30 m/s (cos 60°) = 15 m/s horizontal velocity

If the projectile starts at 26 m/s in the "y" direction and gravity slows velocity by 10 m/s each second, it will take 2.6 seconds to fall to the ground, totaling 5.2 seconds in the air.

Since the rocket travel in the air for 5.2 seconds at 15 m/s, it will go 78 meters before hitting the ground (5.2 x 15 =78).
Products being sold are not toys. They are for Educational / Labratory use only. They are not for use by children 12 and under.
