God I wish I thought of that, I always opened up the tape rewinded it then sealed it back up again using my acid saturated piss to burn it together again.

But not seriously I used a bunch of things to rewind it but I don't see how a pencil would work since both ends are round, so if it did fit inside it wouldn't work because it wouldn't be able to hit straight across, or at least it would work as well as my finger nails or my tongue.

Both ends ARE round, but did you notice how the pencil isn't completely round throughout the whole thing? It flattens out on every side, making it quite easy to catch the grooves.
