Off with a pop! After electrolysis of water into H2 and O2 gas, a filament ignites the gasses and sends the rocket skyward. The waste of this process is pure water that is reused on the next launch.

This is the solution to the prior puzzle

    Being made of plastic, it looked like a toy. It is a toy! For a hobby I mean. Great puzzle.

    Very cool. So the short impulse is overcome by the light weight.

    I remember building my own electrolysis rig out of an old carbon battery electrode, a couple of test tubes and a big glass jar.

    Hmm… Might be time to do that again on a larger scale with a solar panel…
