A very simple slingshot that is best used shooting people ;) (co-workers perhaps)

Step 1: Supplies

To make this, all you will need is: Scissors,An elastic (has to be fairly strong), A piece of scrap cardboard-like material (I used an empty pack of gum), A pencil, pen, etc. (optional)

Step 2:

Empty your pack of gum (or get an empty one from the start), and take that or whatever you decided to use. Now take the scissors and cut a rectangle out of it (size depends on the size of the elastic). Then punch two holes in the sides. You should have something like the picture.

Step 3:

Now take the elastic and push one end of it through one of the holes (you may need a pencil to get it through), then out the other hole. Pull both sides of the elastic so that it is tight against the back of the rectangle.
