Everything is a conductor if your generator has a high enough frequency.

The teacher was explaining about conducting and not conducting, and we had a battery with lamp thing to test on various objects. I of course had to test this on a pencil and discovered semi-conducting. That was a serious “not today” sigh from the teacher.

How did that work?
Doesn’t pencil lead material just work as a resistor? It’s mostly graphite and clay, and shouldn’t have the required structure to work as a semi-conductor.

In my case it gave off a few sparks at the contacts what really makes it interesting for young me.
