The Flying Saucers ride used magnets to levitate the bumber cars not air, just look closely at the pictures there are NO holes in the floor for air to shoot up through. Look closely and you can see the holes in any air hockey table; no holes = no air.

Basically, the Flying Saucers ride was Disney’s answer to bumper cars. When the ride starts, air would shoot up under the saucer and lift it up off the floor
