I am going to show how to create your own Nerf Darts without spending tons of money.
Step 1: Materials
You will need: 1/2" Caulking foam (You can get at most hardware stores for about 3$), Duck tape or hockey tape, Scissors.
Step 2: Cut the Foam
Now you have to cut the foam to about 2" long. USE SHARP SCISSORS!!!
Step 3: Wrap the Darts
Next wrap each piece of foam about two to four full rotations. Wrap them really tight if they keep coming loose put a dab of glue under the flap.
Step 4: Finish
You can also blow dry them so they stay straigh. I will sometimes push a bb into one end for more weight.
