Jet engines and rockets are different means of propulsion. A jet engine takes in air, compresses it and mixes it with vaporized fuel. The air fuel mixture is ignited and produces thrust out the rear of the engine. A rocket uses fuel wich is burned and produces thrust with no air intake. Rocket fuels can be solid, liquid or compressed gas.
A stomp rocket is a toy rocket that is powered by compressed air. This is a trademarked name, the owner being Fred Ramirez, President of D&L Company. The term 'stomp rocket' has been genericized, much like 'xerox' or 'kleenex'. D&L manufactured the first stomp rocket ever in the early 1990's and since then, many clones have appeared. Stomp rockets have an air bag that attaches to the rocket by a tube. When it is stomped…
