This Playsteam replacement is for the Water Powered Rocket (no. XP00401) that teaches about cause and effect of water pressure in a vacuum. Just fill with water and hit the plunger and watch it fly! A fun and interactive learning toy that will not only teach kids about science and physics, but help them get healthy amounts of exercise (recommended for outdoor use).
This set comes with replacement bottle, cap, pressure valve for filling, washer, o-ring and 4 wings for aerodynamics. An amazing present for birthdays or any kind of celebration or a day at the park. Kids will be having so much fun they won't even know they are learning about physics! That is the Playsteam philosophy when creating their toys, hours of play time turns into learning time.
