I need help attaching a syringe dart plug. One way is to create a plug is with synthetic hair to match this dart. I need suggestions on how to attach the hairs to the dart. I think feeding the hair through a funnel would allow me to wrap line around one end to secure it to the dart. I then use a smaller funnel that I glue the hair into. This allows me to reuse darts by detaching the smaller funnel and injecting air to pressurize the dart again.

I know there are kids on this forum but to those who know about ballistics, any idea how these fly? I know a 1cc dart would fly farther than a larger cc dart but what kind of range can I expect? Given that I use out of a .50 caliber 8 foot carbon fiber blowgun with maximum volume flow. Any suggestions on how to improve range?

I'm not asking you what the use is. I'm asking how to improve its design. If you have any relevant ideas, please let me know.

This board is rather slow. Here is a video for the basic idea behind constructing the air pressurized dart syringe. Ideally, I want to be able to project the dart farther than 20 yards so I decided to cut down on the cc/volume of the dart from 3cc to 1cc. Keep in mind that the ccs are doubled because you have to use two syringes to create a dart, one to contain the liquid and another to hold the pressurized air. I think that the ballistics will be off since the weight of the dart is not distributed evenly (liquid in front, air in back). I was thinking of using a heavier gas but then came across a chemically induced form of injection with sodium bicarbonate and acid found here. I am cautious to attempt this because no propellant can mix with my injectant. Any thoughts?

I have a thought. Perhaps if you give us a few details on your planned project (objective) we will be less fearful that your intentions are pure evil and thus become more willing to contribute. Who knows?
