Step 5Attach the motor to the battery
Scuff up the bottom of the battery a little, I think it should help the solder and hot glue adhere. I used a file to mar the surface. Make sure you clean it afterwards with a little alcohol. I believe acetone will work better than rubbing alcohol, but use whatever you have around.
Your motor should have two wires coming out of it. Solder one wire to the bottom of the battery. I had trouble getting the solder to stick, so I reinforced it with a little electrical tape (which you can't see in the pictures).
