Nothing special or powerful just an idea I came up with to make use of some old PVC and fittings. Basically its a balloon powered BB laucher which requires no pump, no tyre valve and no PVC glue (the parts are held togheter by wrapping ptfe tape around the pipe and jamming it in the fitting).
You close the ball valve located next to the handle (in crude trigger position).
You remove the stopper from the back end of the gun (a pen in my case) and blow through the hole in the endcap. This causes a balloon to inflate at the bottom of the handle (it was previously crammed inside the handle). Once the balloon is big enough hold the end and put the stopper back in the mouthpiece. Now its locked and loaded, put a BB down the barrel (Mc Donalds drinking straw) and open the ball valve to fire.
By opening and closing the ball valve quickly I get about 10 shots from one fill , but I have to load a BB for each shot (have no clue how to make a hopper for a straw).
Its called the annoying keyhole gun because I first used it to covertly fire small spitballs at a friend through a keyhole. It took him 5 shots to actually realize what I was doing.
This thing can be fired and refilled relatively quickly. A handful of people armed with them could have a laugh I suppose, like a mini paintball game.
Now if only I could make some sort of hopper....
So there you have it, the lazy-man's peashooter ..enjoy.

The whole gun with the balloon deflated.
To the left the barrel, to the right the pen I used as a stopper. You can use the straw for size comparism. |

Lol. I love it. But im guessing it doesnt have a lot of power behind each shot?
For more powerful shots, try thelong baloons that make baloon animals from, those things hard hard as hell to blow up unless you have a pump. Though im not sure it will give the same proformance after you re-inflate it. Eh.

| For a hopper just take another McDonalds straw and attach it to a hole in the barrel. This will function as a clip. You can try melting the 2 straws together just don't melt it to much.

| Where I live there is a game caled фуниики(funnels).A group of cildren each one 'armed' with а tube(калам) and about 100 paper funnels go in old construction site and shoot each other.I dicided to make a superior weapon(a sniper) and that's how I reenvented the spud gun.

Hehe, yeah, we have that same game over here. Such a crude weapon is actually quite powerful, as an average kid can shoot the funnel to about 40 yards, tho' CQB tactics at around 20 yards are more common. I've seen some pretty nice designs, too. Double, triple, quadruple shooters, magazines, snipers, MP5s etc. Kids can be quite inventive. Man, if I knew back then what I know now...

| Well obviously its power is limited but different balloons cause different pressures. After a few shots the balloon gains a permanent extension but its cheap and easy to replace. And trying to stick two straws togheter is very hard to do but I have another idea for the hopper its a sort of pump action design in which another straw will sit on top of the barrel lengthwise and by pushing BBs through the open end the BBs will fall into the barrel/

| Oh come on.Pump action?I can tell you from where to take and exteremaly powerful gun comperad to this.You get out of your house and go in the first toy shop.There are super strong spring operated airsoft guns.All of them bolt action(incredible huh?).That's it for now.When you become 40 I'll tell how to make a higher class weapon-an incredible pellet gun

I have two airsoft guns both pistols, but a couple of my friends have full auto M4s. Over here you are allowed to own and use them, however getting them into the country is the hard part due to certain import regulations.
As a matter of fact, I got into spudgunning to build my own airsoft weapon, a rifle with the ability to switch between full-auto and a bolt action single shot. I could very easily buy one, but I would rather make one simply to know that I can.
And when I said "pump-action", I didnt mean anything complex just a small cheap and easy way to reload BB s into a barrel with a shotgun style tubular magazine.
