Water rocketry has inspired generations of scientists and engineers. A bike pump, launcher, and a little ingenuity can launch soda bottle rockets hundreds of feet in the air.
The Marimo Labs Water Rocket Project brings water rocketry to a new generation with a globally-compatible 3D-printed launcher and a library of modular parts to upcycle soda bottles into water rockets.
