This air-powered projectile is sure to send your students' imaginations soaring.
Solid-fuel and water rockets just have too many variables for accurate study of Newton's Laws. So explore projectile motion with this 100% safe, chemical-free air-powered projectile.
Accurate and repeatable to an amazing degree, 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, and Super - so you can vary launch speed for different experiments. You can even build a launch pad (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 Launch Pad
This easy-to-use launch pad utilizes six wedges (sold separately) that let you vary the launch angle from 30 to 55 degrees (in increments of 5 degrees), so you can explore different aspects of projectile motion and Newton's laws. Comes unassembled.

Here's a lesson you can try with the air-powered 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 degrees. 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).
