Pressure Bottle Rocket DIY. 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! Summer. Boredom Busters. Kids. Science. Activities. Outdoor. Play. Easy.
SPACE WEEKThese water rockets are out of this world! We love the idea of turning these water rockets into blank canvases for each child to design and decorate. What a fun idea for a birthday party activity, too!
