hear me out

so a couple years ago I had a shower thought, we could actually make hoverboards, like the flying ones, if we had strong enough magnets.

Like if you get a south pole of a super-strong magnet, put it on the bottom of something, then get another one and put it on the ground, wouldn't that make it float?? If we could find stronger magnets or make stronger magnets couldn't it eventually lead to flying cars or sum? To make flying cars we would have to put magnets in the road tho.

idk I was just staring off into space and remembered that for some reason
