Building the guns are really easy and require very few tools. The only real tool needed is a way to cut the PVC pipe. A PVC pipe cutter makes life easier, but you could use anything that can cut through PVC.
For the guns that I built I made the following cuts:
- 24 inches of 3/4 inch PVC pipe
- 2 3/4 pvc endcaps
- 2 3/4 pvc tee
- 2 3/4 pvc 90 elbow
- 5 2" x 3/4 pvc pieces
- 1 7" x 3/4 pvc piece
Once you have made your cuts put the gun together as the following pictured shows:
There really isn't a wrong way when building your marshmallow shooter. As long as you can put a marshmallow in one end and blow it out the other, any thing you do will work out just fine. This is why I call them linkin logs for adults.
Once my shooter was all assembled and my kids were done with theirs we had a marshmallow war. Each gun only cost a little over $2 dollars and my kids loved the shooters, and you will too.
