Introduction: How to Make a Deadly Dart for Nerf Guns
you need a nerf dart, and thumb tack. if you want to test it you need a target and compattibale nerf gun
take any average nerf dart and carefully, using scissors, cut off the tip where the point or suction cup is(btw this also works on buzz bee and other brands).
now, take the thumb tack and place it into the part where the end was, point sticking out. load it into your gun, and depending on the dart and gun, this will stab into plywood and other materials it also breaks glass when used to its full potential
