Me too. Since bubbles rise it makes sense for the radiator bleeder.

This is with front end on an upward sloping driveway and on wheel ramps. Almost dented my garage door with that manoever as the ramps slid forward. Also still nothing came out of thermostat bleed screw. I think I'll give up on this and just close everything up and keep my eye on the gauge and the refill tank.
