    Hmm according to myth busters, it does work if you have a giant fan and sail, just much less effectively than just the fan. Since the sail is acting as an inefficient air redirecter, kinda like an airplane thrust reverser.

    Also, using the leaf blower on a skateboard should work even better, since the air is coming in though the side instead of straight back.

      i think the mythbusters result goes against the spirit of the myth. yes you “can” blow your own sail, but it’s never going to be as effective as shown in cartoons and such, or just turning the fan around like a normal air boat.
