Marshmallow Gun! Take your parts and use the above picture to put them together to make your gun. This is a very simple gun style. If you want a different style, all you would need to do is buy a longer length of PVC pipe and some more joints depending on what shape you are trying to achieve.
Homemade Marshmallow Shooter Kit - The comments on the blog crack me up. Some should be taken seriously though. Might be a choking hazard for the little ones...just like anything SUPERVISE your kids! Supervise and have fun with them!! =)
