For every action there is equal and opposite reaction. If you blow a balloon and let it go (without tying the end), the air enters the balloon in one direction and the ball goes in the opposite direction. Rockets use this principle. The push to the back end pushes the rocket forward.
The missiles we are starting construction, to generate enough pressure and releasing that pressure very quickly. They generate pressure pumping in air or chemicalgenerating reactions (gaseous products).
Let's begin!
Seltzer Rockets: Place an Alka-Seltzer tablet in a Fuji film container blank (black Kodak canisters will not work) and fill one third with water. Working quickly, invert cap and sidewalk. Stand back ... POP! You will find there is an optimal water level for maximum height. If you work quickly, you can get about four launches from one tablet. What happens if you try to two tablets at once?
Paper Blow-GunRockets: Make a very long straw by joining two straws with tape. Roll an 8 ½ x11 "sheet of paper in a long tube and tape shut (the smallest you can use the card to help a wheat roll). Fins Triangle Cut cards and hot glue one end of the cut rocket. For the nose, made a circle card. And 'possible to reach the inner diameter of the roll of tape to trace a circle well. For a flat circle into a 3D cone, begin to cut the circle into two halves, but stop cut whenthe center. Slide closed the door, the other one (the shape of nose) cone and tape. Pile much glue in the cone and add the long straw and wait to dry. Slip the straw inside the tube and seal the nose of the rocket body. Once dry, blow into the straw, to check for leaks. Should not be able to blow through. If you have a loss, go back and correct immediately. Otherwise, slip over the metal tube and blow. If you have one, is a nozzle from a tank or a compressor to blow airthese missiles hundreds of feet in the air! If your straws come loose, simply cut the rocket body just below the nose and rebuild the straw cone assembly, fastening in place when you are ready.
Slingshot Rockets Punch a small hole in the bottom of a black Kodak film. Chain 5 rubber bands and place one end of the chain, the elastic through the hole from the outside, it starts with a paper clip so that it can not slip through the rear opening (like a stick). Hot gluethe canister in one end of a 6 piece of ¾ "foam pipe insulation and the volume of the tape with a few turns of tape. The rubber bands should be attached to the pipe foam. Attach triangular foam fins with hot glue to the opposite end. To begin, pull the hook the rubber band on the thumb to go to leave behind, and!
Puff Rockets: Grab a clean, empty shampoo or lotion bottle. Make sure that the bottle will give you a good flow of air from the top cover when you squeeze it. They areIn addition, two straws, one slightly smaller than the others. And a small piece of foam. Insert the straw into the smaller hole in the lid. If you have trouble, you rub the hole or just the cap and seal the connection with a piece of clay or a lot of hot glue. Place a small piece of foam into one end of the straw bigger. Slide the larger straw (your launcher) on the smaller straw (your launcher). Press hard the bottle! Damn! Which bottles work best? The length on the straw? (We had aRocket clarified that 25 feet).
Micro Paper Rockets: Spiral Wrap to ensure a thin strip of paper around and along the length of a wood pencil and tape (you can turn a straw instead of your naked body rocket paper, but then you need something more Straw small tube launch.) hot glue triangular fins made a tab on one end. Fold the opposite end over twice as safe and comfortable with a ring of tape around the nose. Insert straw in the rocket body and blowhard!
