Now, this isn't from-scratch, but more of an adaption for the darts. FYI, I only know that these work in the Longshot, any other guns will have to be tested by you.
This is my first Instructable, I'm not gonna say go easy, but don't ream me out, ok?
Step 1: Materials:
The weird part: Crayons. Normal Crayola Crayons.
Possibly some scissors.
Step 2: Preparing Your Darts (or Tubes)
Step 3: Weighting Your Darts (and Sealing Them)
Ok, this is a REALLY difficult step.
Take a crayon, doesn't matter what colour, and break about a quarter off.
Then, work the crayon into whichever end of the foam tubes you want, until it's flush. It will look a bit bulged out, but don't worry.
Darts that are weighted, and fly pretty good, too!
Ok, well, thanks for reading, don't forget to rate!
P.S. Sorry about blurry pics, I have shaky hands.
