In this Tutorial, i will explain how to create a basic gauss cannon with various materials. This can be very dangerous with high voltages. Be careful. The higher the power, the faster the projectile. This is my first instructable.
Step 1: First Step
FIrst, Get a tube, it doesn't matter what material, and get some wire. Take some black wire tape, and tape an end of the wire onto one of the ends of the tube. Start wrapping the wire around the tube, and keep the wire close together and very tightly wound. Once you get to the other end, start wrapping the other way, and stop about two-thirds down the tube. Move down the tube about one third of the way down the tube and wrap the wire until the end of the tube. Now cut the end of the wire, leaving about 5 inches of wire off the tube-coil. Now tape the end of the coil, so it doesn't go loose. Make sure your finished result looks like the picture below.
Step 2: Step Two
Now, attach some wires to your two wires coming off your coil, and then attach the two wires you just attached to your coil, and attach them to a power source.
Step 3: Step Three
Now put a metal object in the end with the thinner coil, and it should fly out with a changeable speed.
Now you have an effective gauss cannon that can shoot various metal objects with great speed. Enjoy!
