This happened at my house.  DIY Marshmallow Guns.

Inspired by this photo and completely made by Christopher and Grandpa!

Here’s how they did it (in Christopher’s words):

1.  You need 1/2 inch PVC pipe, 2 elbows, 1 T, and 1 cap.

2.  Tools:  Pipe cutter or some way of cutting the pipe, tape measure, and a pencil.

3.  Measure four 4-inch pieces of pipe and one 7-inch piece of pipe.

4.  Cut the pipe at your marks.

5.  Put a 4-inch pipe into the bottom of the T.  Cap it.   Put a 4-inch pipe into one side of the T.

6.  Put an elbow on the end of this 4-inch pipe.  Put another 4-inch pipe in the other side of this elbow.

7.  Put the last 4-inch piece into this elbow.  This is your mouth piece.

8.   Put the 7-inch piece in the other side of the T.  This is your barrel where you load your marshmallow.

9.  Push it together tightly or glue it.

10.  Spray paint it.

11.  Load your mini-marshmallow into the end of the 7-inch pipe.

12.  Blow hard to shoot your marshmallow.

13.  Have fun.
