Step 1: Remove the battery from the cordless drill and look up inside. You should see 2 terminals where the battery provides power to the drill.

Step 2: Use the aluminum foil to fashion make-shift wires that connect to the terminals. (Salvaged copper wire is even better if you can find some).

Step 3: Secure your drill to a surface like a piece of 2" x 4" with the trigger pressed "on." I used plenty of yarn to hold it down tight.

Note: The trigger needs to be on and the torque setting at its highest.
