Nice video, as usual! Welcome to the site!
Ha! I am just a man trying to follow your lead on this blowgun stuff... got ya book marked for making my paper darts in the future...Who are you? Nice video man!
You know I was thinking the same thing... I had in mind a glass tube may work well... just have to think of a way to protect it from breaking maybe a copper tube wide enough for the glass to be inserted... anyway its just a thought not sure if it will go further than that.Lookin at the tube in your video caused me to ask a question. Are polished interior surface tubes or non-polished tubes better? When I say better I mean in regards to the amount of friction resistance on the dart. Hmmm.
I could see this but on the flip side a non polished surface would allow more air to pass around the dart. Less friction but also less of an air seal. hmmm Looks like we may have a lot of experimenting to do.The reason I asked is that it seems that friction is often reduced on non-polished surfaces. As an example, it is usually easier to slide an item across frosted glass than standard polished glass.
