Water Bottle Rocket Fins

You do not need to be a scientist to be able to make a bottle rocket, but you must approach it as one, in the sense that you need the right tools and materials in place.

First collect all the equipment you need to build a rocket. These include a bottle of course. Any will do, but a 1 liter bottle of soda size is preferable.

You'll also need a bottle of rubber cement, paint thinner (1 box), a roll of tape, a clamp (1 inch) and a record of Manila.

You also have the following: a pair of 2-inch nails, two pieces of wood measuring 2x4x12, and another 6x1/2x18, four sheets of balsa wood (6x4), five screws, an inch long.

An electrical junction box, a 3 "steel thin (about 1 / 8 inch in diameter), a 12" string, a copper tube 12, and a cap test tube. In this project, the size must be 4 with an opening in the middle.

Regarding the tools, prepare a compass, drill scissors, sandpaper, hammer, marker light, air compressor, jigsaw, and a screwdriver. The size varies depending on the wood screws that you have selected.

To build the rocket bottle, start by washing and drying of the soda bottle. Use paint thinner to remove all the glue and remove the labels as well.

Take the balsa wood, and use the market to highlight form 5x3 (triangle). Use a jigsaw to cut out the shape, and apply sandpaper to smooth the edges. These serve as your rocket fins.

Glue the fins on the bottle with rubber cement. Make sure they are equidistant from each other. The masking tape will be used to straighten the fins.

Take the compass and make a 4 "circle. Use the scissors to cut a line from the outer circle to the center. Fold funnel. Colle, and add a bit of tape. Put the top of the bottle and you have the configuration of the nose. Let the glue overnight and you can remove the tape.

Make a launch pad for the rocket bottle is easy. Take the 2x4 wood and cut it in half. Set them so that each is about 18 inches apart from each other, get the 18-inch wood and put it on the 2x4 so that both parties rely on it. Use the screwdriver to drive screws into a table of 18 inches. Repeat the process on the other side, and the platform is completed.

Take the junction box and inert so that the junction box is connected to the platform. Drill a hole in the box so that the cap test tube can fit in. Put the cap away. Place the copper tubing into the stopper. Connect the air compressor with the tubing using the hose clamp.

Get the wire and shape into a horseshoe. Attach the chain to the center of the horseshoe, and put in the electrical box. Drill a hole in each piece of 2x4 wood, and the platform of the bottle rocket is finished.

Take the ramp to the outside, and hammer a few nails into the base so that it is fixed to the ground. Pour 20 ounces of water in the bottle, put a pin in his neck, the air compressor to 45 psi. Pull the string and watch your fly Bottle Rocket.
