Haha these Halloween videos pop up all over the place around this time! Cool stuff.
Little question. Today I found a small vacuum cleaner in a garbabe, grabbed it, took it home and plugged it in, and it worked. So I ripped it apart and got the motor out of it

It will be used for something cool but I'm not telling yet

I took the two wires connecting the motor off, the kind that slips on easily, and I'm wondering if the motor will function no matter which prong I put the two wires on, if it just switches the direction of the motor, or whatever. Thanks.
