Step 9: A whacking stick!
Now get your skewer or stick and wrap it in aluminium foil. Connect a new alligator clip to the bottom of the skewer, and make sure that it is clipped on to the foil.
Connect the other end of this alligator clip to the 'earth' section on the Makey Makey (along the bottom of the board).
Now when you tap the skewer against the foil squares, the different arrows will be activated. Play the game to see your new controller in action.
