Physics of Hurricane Balls

    Physics of "Hurricane Balls"

    Two ball bearings are welded together, placed on a mirror, and blown upon using a straw.
    The RPM's reportedly can reach 10,000 rpm's.
    There are numerous vid links, here's one:

    Anyway, I know this can also be done with marbles expoxied together.

    Before posting this I searched Google using the terms "physics hurricane balls" as well as here in PF with the terms "hurricane balls' No joy on the physics of how they work.

    Any insight as to how blowing on them through a straw can effect a rotation of these things to 10,000 rpm's? Thanks.
