Marshmallow shooters are one of the most fun things to build and use. This is an instructable on how to make a marshmallow shooter that looks like an AUG assault rifle. It's automatic rapid fire. Gravity fed magazine that holds up to about 9 marshmallows.
You will need to go to a hardware store and get some PVC pipes (obviously). Get a few sticks of 1/2 inch piping and cut them (using either hacksaw or pvc cutter) into these quantities:
one 8.5* inch pipe (this will be your barrel) two 2 inch pipes (this will be part of your scope) four 1.5 inch pipes (these will connect your T pieces/intersection pieces) one 4.5 inch pipe (for your handle) one 5 inch pipe three 3 inch pipe (part of your stock) one 4 inch pipe (part of your stock)
*all these measurements are estimated so make adjustments if needed. Then get some pipe connections:
six T pieces (7 recommended for a scope piece) two 45 degree angle pieces three couplers one intersection piece/piece shaped like a + (this is used if you don't want to use your 7th T piece) two slide on caps
Other things you need: tape (any kind will work) clear piece of thin plastic (or any thing you want to use for a scope sight)
