    I have to make a bubble blowing machine for an engineering class. How slow would you all think the rpms of the fan should be to blow the bubbles out. I was thinking about just wiring a comp case fan up, but I seriously doubt I can cut the rpms low enough. Any suggestions? thanks.

    Get a small fan, like the 40 X 40 X 10 mm #433-Sp401012H from Mouser for $3.95. Only pushes 7.7 CFM.
