Introduction: Knex Plasma Pistol

Picture of Knex Plasma Pistol

This is a knex plasma pistol that I made when I was a bit bored a couple of days ago. Please note that the barrel is from knexmaster#1's M47 full-stock shotgun-so don't have a go at me for it. This can be really powerful with the right amount of rubber bands. It uses about 202 pieces.

Please Note That this is NOT A TOY

Sorry i mean snakes not snake.

The Fishfrog (author)2009-03-27

I like snake but im more into lizards. But still, snake are cute and cool at the same time.

lord voldamort (author)2008-09-24

if you connected both triggers to a trigger like in gorkems's sniper you could shoot both at once.

DrWeird117 (author)2008-08-19

It makes me so sad when i kill grunts in Halo 3. They get scared, call me a big bully, start crying, and say leave me alone. I dont like to do it.

Dont kill grunts There are plenty of other things that shoot you

cause it's made out of KNEX. if you don't have enough of a brain to figure that out, i don't know how you managed to build it in the first place.

kaerius (author)mettaurlover2008-08-28

he's kidding, and have you heard of this thing called the "be nice" policy? oh, and you don't have enough of a brain to figure he's kidding?

Vynash (author)2008-06-06

Yes u do

mettaurlover (author)Vynash2008-08-22

Vynash (author)mettaurlover2008-08-22

mettaurlover (author)Vynash2008-08-23
