Bottle rockets: Small rockets that shoot into the air and may produce a report or a small burst of stars. Ground spinners: Spin on the ground and emit colored flames and sparks. Now That's Colorful! Did you know that the colors in fireworks are created by adding different metal salts to...
Liquid-propellant Rockets Dr. Robert H. Goddard and his liquid oxygen-gasoline rocket in the frame from which it was fired on March 16, 1926, at Auburn, Mass. It flew for only 2.5 seconds, climbed 41 feet, and landed 184 feet away in a cabbage patch. Photo courtesy NASA In 1926,...

Firecrackers are fireworks designed to produce sound rather than light and they're often incorporated into the upper effects of rockets.We think of fireworks as entertainment, but the same technology has more practical uses. Flares used by military forces and at sea work in almost exactly the ...
To fire the rockets, the launcher triggers an igniter at the rear end of the tube. The Apache gunner can fire one rocket at a time or launch them in groups. The flight fins unfold to stabilize the rocket once it leaves the launcher. The rockets work with a variety of warhead designs....
How many million pounds of thrust were on the Saturn rocket? How many rockets have landed on the moon? How were the Apollo spacecraft control panels illuminated? How did the space race start? How does the asteroid belt stay in orbit?
Last November, when two rockets fired from Gaza landed in Israel, they were initially attributed to a “mishap” – possibly triggered by lightning during stormy weather. There is no such excuse for the 40 or so rockets launched on Israel by Hamas over the weekend – some 30 within a few...
If you are curious how often rockets are fired into Israel, then check out the timer we created. It might open your eyes a bit.

While many of the same design, aerodynamic and piloting factors that apply to powered airplanes also apply to gliders, that lack of a motor changes a lot about how gliders work. Gliders are amazing and graceful machines, and are about as close as humans can get to soaring like birds. If ...
