I launched a water rocket with pure hydrogen gas and this is what happened. ideally, a rocker should have a 2 part hydrogen to 1 part oxygen mixture to create a stoichiometric burn. But, I made an electrolysis cell to turn water into hydrogen and wanted to find out what would happen if I tried to launch a pure hydrogen rocket without oxygen using a plasma igniter. it didn't get very high but it worked! #science #sciencefun #scienceexperiment #almostspacex | Stephen Clark
