I want to roll a ball on a material to get the latgest static charge in the ball

templedog

But I don't know what is the best material to use for a ball and flat surface. I was thinking glass ball and typhlon tape at one point, but I have no idea.

Can a rolling ball, roll over a surface and get a charge? with the very low friction?

any insight on this, please help..

a glass ball rolling (or rubbed) on hard tough teflon? will that really create static electricity?
