mulforce90 teaches you how to make a spud gun. For this you will need a small stick of glue, a pen, a lighter, pliers and a screwdriver. Take apart the lighter to get to the sparking mechanism. Use the pliers to remove the bottom of the stick of glue. Insert a thin tube from the pen and you can also glue it inside. Drill two holes in the middle of the glue stick and add 2 thumb tacks. Glue the sparking mechanism at the open end. Now you only have to insert a piece of paper or a small projectile in the front, use hair spray inside and use the sparking mechanism. Now your spud gun is done.
