Marshmallow Guns Options

[BGOAT wiz]

Is this a new thing or did I just totally miss the ball on this one. so I went to a car show a week or so ago and some guy was selling something made from pvc pipe. I asked and he said it was a marshmallow gun. was selling em for like $8 or some shit. I was like I will go buy som pvc and do it myself for cheaper they were rather simply designed. so I decided today to check it out and see if it's an upcoming fad or a fad thats passed. seems like it's up and coming I dunno. so that why I am here to ask if anyone here has done this or knows about it. I also found a decent site w/ guns based off of real guns. http://www.mmgunworks.com/ cool place and some pretty decent guns. so ya comment please.
