- How to make a homemade rocket launcher - Materials: 2 - 3 paper clips 2inch dia. 4-6 foot long rapping paper tube. 4 "AA" bateries 1 paper towel tube 4 or 5 wires (I forget) 1 switch 1 piece of cone shaped styrofoam ~ of model rocket engines. ~ of ignighters First we must make the electrical launching system. Take the paper Towel tube and cut in so you can fit the batteries in it nice and snug. Once you have taped that together, tape a wire to the end of the positive side of the end battery. There should not be any paper towel tube sticking out farther than the end of the battery. Now attach this on the tube about 3 inches from the end. On the negative side of your battery tube make somewhat of a flap on the end so that you will be able to tape an exposed wire on the inside of the flap. This will act as the ignition button. Next, take a wire and attach it to the exposed wire that is on the flap. Run this wire through the end of the tube and attach an alligator clip to it. Now for the safty switch. Attach the wire from the positive side of the batteries to one side of the switch. Now take a wire and run it from the other side of the switch to the inside of the tube. You must also attach an alligator clip to the end of this. Now take your cone shaped peice of styro foam and fit it into the end of your tube. This should fit nice and snug and should be extended anywhere from 1 to 6 inches out of the back of the tube. You should use the paper clips to attach the cone to the tube. *Note* - you should place tape on the end of the cone on the inside to keep it from melting or catching on fire from the rocket engine. Now you should have something that looks somewhat like a bazzuka. **NOTE** This is not guided in any way, shape, or form. So whatch where you point it!! This file is just for fun and enjoyment!! This IS NOT a guided missle launcher!!!!!!!!!! These engines go crazy!!!! Now to shoot it switch your saftey switch on fire and press the flap down so the wire touches the battery and Whooooosh!!!!!! Have fun!! -----====>Vortex
