This mini rocket can be launched again and again with the explosive power of bicarb and vinegar. The Fizz Rocket is filled with these 2 household items which create a chemical reaction that makes a build-up of carbon dioxide which shoots out the base of the rocket and shoots the rocket up. Using the included scoop, simply put 1 small scoop full of bicarb soda into the rocket base, add a large scoop of vinegar into the base, clip the rocket onto the base then place it on the group and wait for lift-off! Assorted colors. Suitable for outdoor use only. Ages 7+.
