These were super easy to make and have provided hours of fun. They cost about $1.15 a gun. If you would like to make one you will need:
13 inches of 1/2 inch PVC pipe ($1.62 for 10 feet)
1- 1/2 inch T Joint
1- 1/2 inch end cap
Here is a close-up so you can see where each piece goes:
I used PVC pipe cutters to cut these (If you don't have them they cost about $10 OR you could use a saw)
FYI: The cutter look like this:
My little boy and I really had fun with these, we had a bunch of friends and family over too!
If you don't like the idea of guns or don't want to mess with cutting PVC pipe Come Together Kids has an even more simple way to have fun with marshmallows.
