I am making a dart gun this weekend but i am not sure what material will make the dart go fasterI know that blowing through the one end causes it to go far, but i am wondering if there is something that will make it go through the tube fastAny requests?You need an aluminum tubeThe suggestion of PVC is only good if you\'re making a very short one, as it will sagIt\'s also very heavy in comparisonNo, there is nothing about the construction that can give it more velocityHooking a blowgun up to an air compressor, thought.that\'s a different storyI\'ve pierced a 2x4 with a dart shot with the aid of an air compressorYou would be much better off just spending $20-$30 to buy one online.Other related question
