Ok here's the situation you need to tell your friend something really important like "sally said yes!!" But there on the other side of the class and there's a very nasty teacher watching but that problem can be eliminated with the message in a pencil just say you need to go to the bathroom and give him the pencil on the way out or something like that I don't really know just trying to come up with some uses its cool though so plz like this
Step 1: Popin Off the Cap
K the first step is to pull off the cap or metal thing that holds the eraser this can easily be accomplished by pulling lightly with a pair of pliers try not to damage it too muchh
Step 2: Drill the Hole
Now you need to drill a hole for your message or whatever else you can fit in there just start out with a small bit and work you way up till the desired size is reached
Step 3: Ur Done!
Now curl up a message on a pice of paper and shove it in and put the cap back on then deliver you secret pencil message
