replace L joint at the back with a T joint, then add a piece of pipe about a foot long, after that place the old L joint at the back along with a 4 inch piece of pipe going down, cap that off and you have a stock.

a good twenty yards? that's sixty feet, an I find it hard to believe you can launch marshmallows twenty yards. please load a video proving the distance then I'll believe you.

look at the physics involved. it works. the impulse of the air blowing leaves it with force for while. the longer the barrel, the longer the distance to a large extent. there are some exceptions though.

hey i bet no one has thought about this. hooking up an air compresser to shoot marsh mellows
Jul 3, 2008. 12:34 AMblugyblug says:
everyone does that, and they shove a modded sprinkler valve piloted by a blowgun all pressured to 120psi shooting golfballs, marbles, batteries and only occasionly marsh mellows...

Actually, he was just proving the point that someone has done it and posted it on instructables.
Jul 9, 2008. 5:29 PMblugyblug says:
Nah he posted it before.. go scroll down you can see that he said "like mine"be4

I made one that you pump up with an air compressor to shoot the larger marshmallows. Much easier to fire, and you get a lot of distance:

Jun 5, 2007. 6:01 PMMetal4God says:
OK how about making a true magizene that pushes the marsh mellow up into the barrel
Jun 6, 2007. 5:59 AMbobbyk881 says:
yep i did to

i wold but don't have a camera when i get one i will
Jun 12, 2007. 3:06 PMdemonslayer12 says:
another mod you could try is take a T, make a grip, put 2 1" pieces on both sides of the T and that way you have 2 grips
Jun 3, 2008. 2:29 PMbob the builder #1 says:
you stole my idea!
Mar 17, 2007. 7:59 AMski4life says:
what is the point in buying one if you can make one
Jun 23, 2007. 1:17 PMstraw hat pirate says:
less work and let the experts do it i guess
Nov 1, 2008. 3:51 PMryukaji says:
well you don't need to be an expert to make a marshmallow gun... ski4life has a point. just like the instructions say all you really need is 1/2 inch pvc pipe and connectors and a saw and you can make your own. No offense to the author, but where you placed your magazine on the automatic isn't the best. You will get more power and range if the marshmallow has more time to build up speed in the barrel if you placed the magazine farther from the end of the barrel. Your sniper looks nice though.

A saying in Make vol.4 says "Give a man a fish or teach a man to fish" The quote applies here as well. I cant imagine that this project is so dificult as to require "expert" aid.

i think the marshmellows will go further if you put the hopper by the mouthpiece before the 1st bend

hi I'm new here!

good for you!

Wars would be quite a bit more mellow with these!!
Aug 17, 2008. 3:04 PMenzot2 says:
I've discovered a great use for old AA batteries. Put one in the hopper, and it pushes the marshmallows down just enough to keep feeding them into the barrel. Umm...be sure to put it in ON TOP OF the marshmallows.
Apr 16, 2008. 11:01 PMhawk123 says:
I myself have 1/2 in. piping although a different kind of gun,(semi-auto)not that it really matters but I still can't get the marshmellows to go all the way down the hopper! What about making them skinnier or cutting them smaller? Anything else? Any advice would help, Thanks! John
Aug 9, 2008. 12:34 AMchocolate_zombie says:
let the marshmallows dry out or use mini-marshmallows. if they're dry, they wont stick together as much. and, as i said there, use cornstarch. i love the stuff for all of my marshmallow-related escapades.
Jul 9, 2008. 9:56 AMcodongolev says:
I think cutting them smaller would make them stick. maybe you could put some sort of spring in the hopper to help them along.
