The Hydrogen Rocket With Talking Tutorial. This rocket blasts up to 200', twenty stories high, in the air on hydrogen fuel children can safely create themselves, and it has an audio tutorial that explains the hydrogen creation process built into its launch platform. The rocket's fuel generator uses electrolysis to separate an electrolyte of tap water and citric acid crystals into oxygen and hydrogen; hydrogen, being lighter than oxygen, is collected at the top of the generator and concentrated around an igniter. The launch pad's audio tutorial explains the hydrogen creation process accompanied by a series of lights that illuminate to indicate progress until complete, a launch tone sounds when the rocket is sufficiently fueled for launch. Upon ignition, the hydrogen fuel burns
instantly and cleanly, propelling the rocket into the air, and re-combines with oxygen to leave water as the only by-product of the launch. The crystals enable thousands of launches, and the same water can fuel blast-offs for an entire day. The rocket drifts gently back to earth on spinning helicopter blades which deploy during launch. Requires six D batteries. Ages 12 and up. The manufacturer has confirmed that this item meets U.S. Federal toy safety standards for lead. 20 1/2" H x 9 1/2" W x 11 1/2" L. (2 1/4 lbs.)
