Sci-bits: Pump Rockets Kit

Do you like bottle rockets but hate the mess they make?

Then launch these micro rockets that fly up to 20 feet. Discover Newtonian rocket science. Blast off!

This pump pocket rocket kit includes everything you need to launch safe soft-foam rockets into the sky with just the power of air pressure.

Included:

• One compressible bellow
• One launch pipe with base holder
• Three soft-foam rockets

How it works:

When you press down on the bellows, you squeeze the air inside the bellows. This suddenly increases the air pressure inside the bellows, and air rushes out of the bellows and into the launch pipe, making the air pressure higher there. The high air pressure in the launch pipe pushes on the inside of the rocket, which propels the rocket forward.
