I'm sure most of you guys are like me, in that you've gotten good at pen spinning while zoning out during redundant lectures (really class? you still don't understand derivatives? jesus fucking christ). so I have a question, what's your guys' favorite spinning instrument?

I like using standard Bic mechanical pencils, because the grip is a nice spinning surface, and I can stand having to sharpen real pencils all the time (although they spin very well). Also, bic pens are too light and just fly away

pic related, its basically the only trick I can do, but I do it back and forth pretty quickly so it looks pretty sick
