How do you think, what is necessary to launch a rocket? Launch pad, rocket and.. Of course, fuel. Not simple gasoline, but a special and very expensive rocket fuel. But what about a rocket, that runs on... Water! Unbelievable at first, but this curious gadget is a true illustration to the Third Newton’s Law - “every action has an equal and opposite reaction”.Of course it’s not just water. You must pump air into the rocket, until there will be enough pressure in it to force the water out. Water flow thrusts the rocket upwards (or at whatever direction it is pointed to) giving it needed acceleration to fly.
This gadget is excellent to play, because it needs no special fuel, and you can launch it everywhere you want to. Except deserts I think... You won’t waste precious water in the middle of Sahara just to launch a rocket, would you?
