Building and Launching Water Rockets

Building and Launching Water Rockets

If you want to leave Earth, you have to combat a great force - gravity. Powerful rocket motors have sufficient performance to defeat gravity. We try out how the forces of such large rockets work to propel them into the air on small, home-made water rockets.

Bring an emptied and rinsed 1.5 litre PET deposit bottle along with you, which you can convert into a functioning water rocket following our instructions. We then test how far the resulting models can fly in a flying competition.
