Introduction: Balloon Powered Pen Gun

This is an extremely powerful pen gun that shoots airsoft bullets or the ink tube of a pen, I shot it and got stuck in my wall.
-Be careful and only use under adult supervison, not!

Step 1: Materials

What you need is:
- Pen
- Scissors
- Rubberband
- And a water balloon
(2 minutes)

Step 2: Gut the Pen

Just take apart the pen.

Step 3: Cut the Tip

Use your scissors or a knife and cut the top off. P.S.( You may want to duct tape the hole.)

Step 4: Add the Ballon

Put the balloon on one end then wrap a rubberband around it so it doesn't come off.

Step 5: Insert Ammo

When you cut the top off you should have had a hole insert the ammo in

Step 6: Pull Back

....

Step 7: Fire

...let go...

    very nice dude i used a old mechanical pencil and a party balloon and it works awsome.

    very nice... I took the thing apart and it looks just like a pen now- my secret weapon.

    it is better to use bigger balloon , it will shoot around 13 feet and still stick to a thick cartboard

    easy, cheap, works good
    and every thing you got there most people have at home

    wwwwwwwwwwwwoooooooooooooooooooooowwwwwwwwwwwwwwwwww

    my friend made something like this... but with a water bottle top... he shot hard candy and coins at us... it hurt like a mofo

    This is great, It goes far and really straight. Good job!
