Pikers, I say!!!
Back in the day, (look out, old s*** speaking), when the programming got us all stark raving mad, we devised a semi-lethal "toy", with just push-pins, paper and Scotch tape (cello tape).
Tape a small piece of paper (2" to 3") around the shoulder of a push-pin. That is your dart.
Create a paper tube the size of the back of the dart (the dart will be flared a bit, if done correctly).
Insert dart in end of tube, acquire target, and blow.
Luckily, no one lost a eye before we were shut-down.
