The listing, Marshmallow gun / shooter has ended.
My son and his cousins had hours of fun making and playing with marshmallow "shooters" like this one. It is made of 1/2" PVC piping, a three-way joint and a cap. Place a mini-marshmallow in the barrel of the long end and give it a mighty blow. The marshmallow can travel very far, like up to 10' or more depending on the lungs of the user.
Once you have this pattern, you can buy all sorts of joints, caps, 2-way and 3-way joints, etc. There should only be one barrel, but kids can add on pipe so it looks like a machine gun, an alien gun, or whatever their imagination comes up with. We had 13 cousins (ages 5 - 18) at a family reunion in the woods and this project kept them busy for hours. They each got one plastic sandwich bag stuffed with marshmallows at the beginning. When they were out, they had to collect up more from the ground. Hint: if the marshmallows are a little stale (stiff) they work better sometimes - depends on the weather, humidity, etc.
Cheap, clean, nonviolent fun! If the auction goes over 100 points, I will ship it for free.
