Ever wanted to send a message to someone with a dart, well now you can All you need is a sticky note(the small ones), a pen or pencil and a dart (dart tags darts probably work the best). First, you write your message on the sticky note, write it at the top if you want it to be seen when it is taken out, then flip the note over and roll it up, roll it from the bottom up. Hint: when you roll the note up it doesn't have to be every tight, just small enough so it could fit in the hole of the dart. Then take the note and put it in the dart, and shoot it were ever your want. When you want to take the note out just flick the middle of the dart untill it comes out.
At first I also thought this wouldn't work, I was just fooling around. I have tryed this many times with a nf, a pocket strike (both of the barrel posts were removed) and a big blast, it does work! I don't think this would change the ranges of any gun so I didn't test it.
EDIT: You don't have to use a sticky note, any paper will probably work, its just a sticky note is easier to use because its already in a good size.
