Minus Gravity was working on a pare of Anti-Gravity shoes, when the anit-gravity chip was to big, about the size of the two circles at the end of the board. Angered, he attached them to a piece of wood, which started floating. Minus Gravity, realizing his mistake, gave the board a blast with a gravity gun. Minus Gravity found that he could use his brothers machinery to upgrade this design, he fused a gravity and anti-gravity chip together to make a switch. The boards gravity and anti-gravity switch allowed it to be used when needed.
