A speedy science projectIn this project you will build your own two-stage rocket with balloons. When you inflate a balloon and then release the nozzle, air is pushed out the back of the balloon ...

Balloon rocket The balloon rocket experiment is fun and helps introduce Newton’s third law of motion, which states that every action has an equal and opposite reaction.

Balloons won't replace all rockets, as they can't travel higher than 40km. And even though helium is a finite resource, balloons are more "environmentally-friendly".

Those flying on balloons will remain at a height of 70,000 feet (21 kilometers) for more than four hours, allowing students to perform experiments involving images of Earth's surface or the impact ...

The first experiments will be launched on a balloon, BEXUS 7, in September 2008. The first rocket experiments will be launched in March 2009 on the REXUS 5 and 6 sounding rockets.
