Launch homemade soda bottle rockets up to 30 meters! Perfect for school projects, science fairs, and backyard physics fun.

Water Rocket Launcher:

A water rocket launcher is a handmade launcher that uses water and air pressure (from a bicycle air pump, included) to launch plastic soda pop bottles. Includes instructions with ideas for experiments, such as making an altimeter and testing what happens when water and air pressure amounts are varied.  Adult supervision is required.

Launcher’s prefabricated parts kit with adjustable trigger, and launchpad. Launching the launcher will enable you to propel a 2-liter plastic (PET) soda pop bottle over 300 ft. Launcher supports air pressures as low as 20 PSI up to 120 PSI. Great item for people of all ages for fun, science projects, school classes, parties, etc.

How it works:
Fill the bottle partially with water, attach it to the launcher, pump air using a standard bicycle pump (not included), and pull the release cord. The pressurized air forces water out at high speed, creating thrust that launches the rocket skyward.

⚠️ Important Note:

The Water Rocket model shown in the product photos is NOT included with this launcher.
