Clean dry wool works nicely. (I give all my old wool hiking socks to a
friend who teaches physics to high school physics teachers.)
I think the other key ingredient is Styrofoam. You can get good chunks as
"paper" plates or fast-food containers.

Fond memories...
In 1960, I was in high school. A couple of classrooms had new chairs with a
plastic seat and a steel frame. They were great for generating static. I
had shoes that were good insulators. I could charge up on one of the chairs
and walk down the hall to the lockers and still give somebody a serious zap.
The chairs had 4 big round-headed bolts that went through the seat to hold it
to the frame. As the typical male was sitting down, a certain sensitive part
of their anatomy was closest to the bolt. We learned quickly. I got very
good at hitting a leg of the chair with my foot/ankle as I was sitting down.
