I'm working on a .22 caliber gun, I thought I'd share it with the forums :)
This was made for a science assignment surprisingly :D
What it's made of:
100% recyclable materials.
PVC Piping
Metal tubing taken off a weed sprayer
Wooden dowling (pine)
7cm Comp. Spring
How it works:
To fire it you pull back the roostering lever and push it into place. (fig 1/2) You then load your bullet into the hole inside the gun. (fig 3) When you want to fire, lift the roostering lever out of the slot and it will fire! (fig 4)

All credit goes to me and my mate Zach in the background.
EDIT: For dumb stuffs who don't read the comments:
I ran out of bullets having fun up on my Mum's farm, but I can make a video of it without firing :) I'll get a video of it firing in a week or so.
Actually it is a gun, it fires a .22 caliber round. It works on the basis of a firing pin on the mechanism.
I have fired it.
It hasn't got that much recoil, but half of the recoil it has is from the compression spring.
Molasses, it is hard, it has a large compression spring to make sure it hits the primer hard enough.
The video.
There we go.
TELL ME WHAT YOU THINK OF OUR CREATION
Please rate it x/10 :)
