I got this idea from N-Striker *and Celloman* from (their) idea of shotgun darts from knex.
I have also another idea I came up w/ from Stefans (from Twisted and other people) that you can use Split Shot Sinkers used for fishing. You still put the tic tac down the about lenght shown in step 4, but instead of filling with tic tacs, put (2) split shot sinkers size BB and then put a size PSS-7 sss in to seal it. Note (1): These darts are heavier that regular darts, and Note (2): I have done some testing on different nerf guns with these sss darts. That I know of, this only works on the (air restrictor and spring modded) longshot, possibly the attachment to the longshot, possibly the n-strike revolver thing, and possibly the Recon (small one). I have tested this also on the Recon CS-6, the (un-modded) longshot, and a couple of REALLY small guns, and those didn't work. If anyone would like to test these darts on other guns, that'd be okay.
I WONT BE RESPONSIBLE FOR ANY INJURIES SO DONT AIM FOR THE FACE AND WEAR EYE GEAR IF POSSIBLE.
Step 1: Things you need
1. Nerf darts (duh)
2. Tic Tacs (any kind)
4. Pliers (maybe)
5. A pin or knex piece
Step 2: Take apart
Then, use your fingers (or a pair of pliers) to rip out the little nub out of the center of the dart.
