The initial prototype of our lunar firework rocket (Fig. 1) is ready for testing. It is equipped with a nose cone and fins, and instead of silver nitrate (AgNO₃), we are using potassium nitrate (KNO₃) as an oxidizer. Mixing magnesium and potassium nitrate for flash photography applications has been a standard procedure since the 19th Century, for example. Our updated design now calls for the delay charge of the rocket engine to directly ignite the flash powder in the glass jacket -- simply a common test tube. Therefore, we have removed the plug and cover on top of the delay charge, so the flash powder is in direct contact with the black powder of the delay charge (Fig. 2).
