Hydrogen Gas Rocket

thingiverse

This is a file for a screw on rocket adapter for a normal water bottle. The plug is designed to use a 22mm x 4mm o-ring and 3x 1/8 NPT threads for 1/8 NPT to 1/4 OD push connect fittings. Connect a hose to the one port on the inside and make it the length of the bottle. I added a small hole to put a TIG welding electrode into and I zip tied the 1/4" OD hose to the electrode to keep it straight. I am using a high voltage arc generator to create a plasma arc inside of the bottle. The two small holes are for the electrodes to be pushed through. They should be epoxied into place to prevent any air leaks. Then, put the plug into the main exhaust port. Put some teflon tape onto the threads of the bottle and screw it onto the main fin body. Put a short hose onto the quick connect fitting that doesn't extend through the bottle and place it into a reservoir. Fill the reservoir with water to the bottom of the bottle. Put a hose onto the final quick connect fitting that runs to the top of the bottle and suck the air out of the bottle. If it is sealed, the bottle will start to fill with water. When the bottle is filled, if there is still water remaining in the reservoir and both hoses are submerged, the water should hydraulicly lock inside until the seal is broken by air entering the bottle or one of the hoses rising above the water level in the reservoir. You can then hook the hose to a hydrogen tank or electrolysis cell to fill the bottle with hydrogen (or hydrogen and an oxidizer). When power is applied to the high voltage generator with the bottle filled with hydrogen gas, it should combust and launch the rocket.
