An appalling accident rate [5] led individuals such as G. Harry Stine and Vernon Estes to make model rocketry a safe and widespread hobby by developing and publishing the National Association of Rocketry Model Rocket Safety Code, and by commercially producing safe, professionally designed and manufactured model rocket motors. Model rocketry by ...
The first small-lift launch vehicle was the Sputnik rocket, launched by the Soviet Union, which was derived from the R-7 Semyorka ICBM.

The balloon rocket can be used easily to demonstrate simple physics, namely Newton’s third law of motion. [2] A common experiment with a balloon rocket consists in adding other objects such as a string or fishing line, a drinking straw and adhesive tape to the balloon itself. The string is threaded through the straw and is attached at both ...
BnB Rockets "Boost Glider" Is a perfect example of a gliding recovery system. In some cases, radio-controlled rocket gliders are flown back to the earth by a pilot in much the way as R/C model airplanes are flown. Some rockets (typically long thin rockets) are the proper proportions to safely glide to Earth tail-first. These are termed ...

The main difficulties include cooling the combustion chamber, pumping the fuel (in the case of a liquid fuel), and controlling and correcting the direction of motion.
Charging options: Some flip phones charge by dropping into a dock, which makes life easy when you're at home but a little more challenging if you travel. Others rely on a fairly standard USB ...
