As a kid, there were few toys I loved quite as much as my Nerf guns. My brother and I would spend countless hours firing darts at each other both in the house and out. Unfortunately after a time, our supply of darts would get smaller and smaller. Since spare darts cost money, our parents weren’t too keen to replace them, as they would simply tell us to stop losing them. I’ve since learned that money does not actually grow on trees, and not losing your Nerf darts is a good idea. If you do still lose them, but don’t want to pay a lot for replacements, you can always make them yourself.
Thanks to YouTube user freeridemtb2, you can learn to make roughly 70 or so darts for around $5. All it takes is a little time, some foam caulk saver, a straw, and hot glue. Basically you just cut up the foam into dart-sized pieces, hollow them out, then make a tip out of hot glue. It may be more work than you want to put into it, but the creator believes them to be more effective than stock Nerf darts.
