Introduction: 30 Second Pen Gun

Super easy pen gun. All that you need is a Pilot G2 pen or similar pen. (They have easy access to the spring.)

Step 1: Get a Pilot G2 Pen

Come on people, this step takes five seconds. If you don't have one, you can find them on the ground at school. Once you have obtained this then you can begin with the rest of the steps

Step 2: Disassembly

Disassemble the pen (don't bother with the small white piece at the end of the pen near the clip) That's all you need for this step.

Step 3: Put the Spring on the Writing End of the Pen

Put the spring on the pen.

Step 4: Put the Writing Part Into the "Chamber"

Shove the pen in there- just not too hard. You don't want it in there too hard.

Step 5: Put the Cap Back on the Pen

Put the cap back on- just barely, if you bump it- it will fall off. Then for firing just click the pen and it should get at least 10 - 20 feet depending on how hard you press it. For variation you might want to glue the cap to the end of the writing part.

I like this idea, but it would be nice if there was a way to keep the spring from falling out.

you could tape or glue the spring to the ink cartridge

This is dangerous. I once had a friend who fires this into one guys eye. Be safe while playing with this as it could hurt.

i think its cool i did it with a pen (not the one you had mentioned) and it worked great not 10-20 feet but still cool (maybe 5 feet)
