For my Body Happening, I chose to make a slingshot that connects to the arm. The majority of the slingshot consists of wood and the remainder is elastic, screws, tape, and glue. I added a trigger to it to allow the user to only have to use one hand to set of the sling shot. The trigger wraps underneath of the users arm and just by simply pulling upon the trigger, it will release and shoot the amo. If you look at the front of the mechanism (where the elastic is attached), you will see two cylindrical pieces of wood. You can add or subtract these pieces to increase/ decrease the tension. In the following video, you will see how easy it is to set of the trigger and how powerful the slingshot is when shooting a four inch piece of wood.
