A stomp rocket is a flying toy rocket that is powered by compressed air. Stomp Rocket is a trademarked name, the owner being Fred Ramirez, President of D&L Company. D&L manufactured the first stomp rocket ever in the early 1990s and since then, many knock-off brands have appeared. Stomp rockets have an air bladder that attaches to the rocket by a flex tube. When pressure is applied to the bladder, the air rushes through the tube and into the body of the rocket, causing it to lift into the sky. There are five versions of stomp rockets available: the Super High Performance Stomp Rocket, which travels about 400 feet, the Ultra Stomp Rocket, which travels about 200 feet, the Ultra LED Stomp Rocket, which travels about 100 feet, the Ultra Dueling Stomp Rocket, which travels about 200 feet, and the Junior Stomp Rocket, which travels about 100 feet. The Astroblast was a late 1970s-era toy rocket consisting of a plastic chamber with a plunger on top. An adjustable plastic pipe allowed a foam rubber rocket to be launched at any angle when the user stomped on the plunger. A later adaptation of the Astroblast substituted an air pump and release mechanism for the stomp chamber and plunger. ==External links== *http://exploration.grc.nasa.gov/education/rocket/rktstomp.html 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Stomp rocket」の詳細全文を読む スポンサード リンク
