Someting like (waxed) silk, perhaps?

Nylon is hygroscopic. Doesn't seem like a good idea. PTFE is flexible
when
thin - eg PTFE sleeving. Some of the other artificial fibres such as
dacron, kynar etc. might also be good - I'm not sure of their
electrical
properties.

I have been discussing with some friends about the Oxford Bell with a

to making one. 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.
