I have a better method for making a hoverboard - What you do is make a liberal lay down on his or her belly then attach the board to their back, then place a piece of paper that has some facts printed on it under their face. The liberal will instantly be repelled by the facts and float in the air.
SCIENCE!
Unfortunately after an initial levitation away from the facts, the liberal’s head explodes and the whole thing comes crashing down. They are working on that.
