Product Description
One of our most popular items!
Water is added to an empty soft drink bottle and positioned over the rubber stopper on the launch pad. The car tyre pump pressurises the air in the bottle and . . . the stopper releases the bottle up to 30 meters or more.
The pre-assembled launcher has an adjustable rubber stopper in order to adjust the pressure build-up (and eventual altitude) before launch. Experiment with double rockets and fins.
Biggest advantage is this: There is no need for special rockets as you may use any size empty soft drink bottle. So if the rocket lands on the school's gym roof or in a tree - no worries.
Required: Car or bicycle stand-up tyre pump (does not work with bicycle hand pump), plastic soft drink bottles (any size)
