The simplest trick...The pen spins around the thumb

PENSPINNER

## Step 1: Find The Center Of The Gravity

The center of the gravity can be found easily...just by balancing the pen on a finger

Its Very good if the CoG (center Of Gravity) is in the same place as the CoP (Center Of Pen)

can I has one of your pens??? :P<br />
I'm having trouble catching it. Any advice?
You may be trying it too fast, try slowing it down a bit. Hope that helps.
This hot receptionist at my old boxing/MMA gym showed me this. I worked on it for about half a year and I'm pretty good now. I just randomly go it in class. Cool instructable!
I got a new challange for you...<br/>Spin an X-Acto knife &gt;=)<br/>
those ballsigns yours?
I bought them at penwish.com a long time ago (I didnt know how easy it was to mod them myself <sup></sup>)<br/>
I've been practicing for 20 min and I can almost do it. Although, maybe solving a Rubik's Cube in under a min is a factor :)
Lol i just did it...
Assuming I can now spin a pen, how do I spin a basketball on one finger?
Sry i dun know :P only do penspinning :P

I told this one Asian kid in my calc class, because the was flipping it back in forth... Two days later (A day, B day) he came into the class took the test that was that day, and during the test, i noticed and yelled WTF (actual wording of course) and the teacher was like WTF and I said I was sorry and sat down, after the test I asked him how he learned it... he said Instructables... I know offically hate Andy (not really hes a good friend) but it was funny, it took him 20mins to do what I STILL CANT DO!!!!! Great inst. by the way, even though I still cant do it...
Took me a week to learn!!! (i watched tuts on youtube :D)
really hard, but good though
I've been trying to figure out how to do this since 95, and I still can't do even after view several instructions. Stoopid fingers!
