How to Make a Simple Projectile Launcher

If you've got a sneaky sense of humor, you can have some fun at a friend's expense. Just make a simple projectile launcher small enough to conceal in your pocket. Watch your friend look around in confusion while you casually act innocent. He won't know what is causing commotion around him, where it came from or who's responsible.

    Instructions

    Things You'll Need

    • Plastic wide mouth bottle
    • Scissors
    • Rough grit sand paper
    • Rubber glove
    • Rubber band
      • 1

        Remove the cap from an empty wide mouth plastic bottle. Use scissors to cut the mouth off approximately 1 inch below the collar. Discard the bottle, keeping only the removed mouth piece.

      • 2

        Sand the raw edges from the plastic until smooth.

      • 3

        Remove the largest finger from a pair of rubber gloves. Stretch the opening around the ridges on the plastic bottle top. If done correctly, you can place the bottle top mouth-side-up on a table and it will "wear" the rubber finger like a tall hat.

      • 4

        Wrap a rubber band tightly around the glove-covered ridges, also called threads.

      • 5

        Load the launcher by placing a dried pea or bean through the plastic funnel so it drops into the rubber. Wrap a thumb and forefinger around the threaded area of the cap and hold tightly.

      • 6

        Launch by grasping the ammo through the rubber. Pull back, aim and let go to launch.

    Tips & Warnings

    • Rubber gloves work best, but a balloon can also work in a pinch.

    • Never use this projectile launcher near animals or small children. With full draw it's powerful enough to draw blood. Aim for inanimate objects such as tin cans and use only dried vegetables as ammunition. They're biodegradable and cause less damage than a rock of similar size, if misfired.
