Quick Dump Valve for a high speed Marshmallow Air Cannon

Video showing in detail how the marshmallow cannon valve compares other designs on the internet. The fun videos are of marshmallows and apples hitting stuff. This video replaces the earlier one where youtube didn't recognize it as a wide screen video. I improved the graphics as the old one was difficult to see. This video is produced as a technical commentary for The Marshmallow Launcher in the forum on www.crazybuilders.com. Please rate this video.
