Line them all up (I usually do it in batches of 5 or 10) with about a third sticking over the edge of a desk - then whack the third that's sticking over the end with your hand and send them flying across the room. I once took out 2 teachers and a nearby 12 year old with this technique so make sure you aim well and you might be able to beat my record.
i hold my pencil in the middle and then wiggle my two fingers back and forth and see if the pencil moves up or down then repeat. i can do this for hours cause i always have to be doing something with my hands or feet or else i go a bit squirrely. in other words i can't sit still for more then 30 secs. once i get bored of that I DRAW EYEBROWS. i know i'm wierd.
I normally use my pencil to draw on my folders in class. This lets me judge how interesting a class is based on my scribbles. I highly suggest drawing optical illusions then staring at them.
Well, if I had a pencil and a paper I would like to be drawing something cool but my maths teachers disagrees with me and makes me do a lot of useless exercises.
