1 small hollow cylindrical object (I used a browning the boss 55/70 arrow shaft... Bend before use lol)
Optional - one bottle cap about the size of a Hawaiian Punch cap and I will show you how to make darts in my next video
Step 1: The Really Really Hard Part
Okay so basically cut or drill a hole through the bottle cap and put it on the cylindrical object you have chosen as your nucleus for this project. ( haha laugh all you want at my science humor but at least I'm paying attention in school.) then make a bunch of small holes integer bottle cap evenly spaced. (Or not). And there you have it your blowgun. I have yet to test this on a living animal outside yet because it is -3 degrees outside today but please if your not a lisenced redneck don't go out and shoot a deer. Mainly because your friends won't believe you when you say you shot a deer and it bit you in the nose instead of dying and if your life goal is killing deerzilla then don't use this.
Step 2: Tips
Make a 't' sound when you exhale. It will propel the dart much further that just going pppaaahhhh.
NEVER inhale with you mouth on the blowgun!!!!!
