Water squirters work by pressurizing reservoirs of water with air. As you pump the squirter, it gradually adds air to the reservoir, increasing the pressure. When you pull the trigger, the pressure is allowed to release and a stream of water shoots out!
In this DIY project, we'll learn how to use the exact sample principles found in water squirters to launch a water rocket sky-high! Follow along with these simple steps and you'll be blasting off in no time.
