A high powered redneck tooth brush (don't scrub a hole in your teeth)
YOU SHOULD NOT PUT THIS IN YOUR MOUTH (I was told to say this, if your stupid enough to put this in your mouth, all I can say is have fun explaining that to your dentist)
Step 1: Supplies
you will need:
tooth brush you don't mind wasting
nail (or other thin peice of metal for the shaft
wire clippers (for cutting toothbrush)
Dremel tool (or other rotary cutter)
Step 2: Chop
go ahead and cut the head off the tooth brush
Step 3: Melt
use your lighter and heat the head of the nail, once good and hot push it into the middle of the toothbrush and hold it straight until it cools some and will stay.
Step 4: Glue It Good
mix up some weld and apply liberally, let it dry and present it to some one who has a dremel tool and loves gag gifts.
