This article will show you how to build a hoverboard. • Go out and buy some 50 pound lift magnets. You will need four. I got mine at Black Hawk Hardware. 100 pound lift will work but the 50s will work the best. • Take the wheels off of an old skateboard or go and buy one without them and hot glue the magnets to the bottom. • Then once you have done this, it's time for the soldering! Take a rocker switch and solder that with a copper wire to a 9 volt battery. Do this twice. Solder the positive end to any end of the magnets. Then hot glue these to the side of the board then find the magnetic field line in your garage or and prodominately metal base will work. Turn on the magnets, wait 10 to 15 seconds, then you're up.
