Does the string really have to be a very good insulator? It is long and has a small cross section, and is electrically in parallel with the case of the battery.

One guy can not believe a battery can last 175 years. Anyway, I was wondering what would make a good insulator to suspend the ball. I thought of nylon fishing like, but can anyone think of a better insulator? Obviously PTFE is a good insulator, but it’s not exactly flexible. Nor is sapphire.
