you will need pliers that can cut wire, the wire (welding lead, get at hardware store), and a rubber band to launch it
Step 2: Cutting wire
you will need to cut about an inch of wire
Step 3: Bending
this is the easy step, just put the wire in the pliers and it will bend in the middle. try to find pliers big enough
Step 4: Done
well, there you have it. just put around a rubber band and launch. p.s.- these things can really hurt and go far. i've shot them over 100 feet easy. as long as you kinda snap your hand foreward when you let the wasp go, it can really help.
