Frakking beds -- how do they work? Redditor mememetatata's design is simple but brilliant. It's just two wooden frames with opposing magnets inside. When assembled, the bed hovers a few inches off the ground.
It looks like the biggest problem that mememetatatta faced was that two of the magnets were shipped together. Each one had several hundred pounds of force, so he spent considerable effort separating them -- and photographing that part of the project.
