A stomp rocket is a toy rocket that is powere 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 has not stopped since. Since then, many clones or knock-offs have appeared.
