Hi CTD123,

Your best bet is to use two ordinary flashlight batteries. (Like "AA" or "C" batteries). You can buy a plastic battery holder for them at an electronics store like radio shack, or you can make one yourself. You could probably probably get away with taping stripped wires to the battery ends to make a connection. You want to connect them like this:

(motor +)-------(+ battery - )--------(+ battery -)-------(motor -)

Not sure what you have in mind for the base. Something like carboard, tape, and plastic drinking straws might work. Since you've only got a few hours to work on it, household objects are probably your best bet.

Good luck!
