SUMMARY

The forum discussion centers on the construction of a Van de Graaff generator, emphasizing the materials and skills required for DIY projects. A key recommendation is the use of plastic-coated fabric, specifically from hotel shower curtains, which outperforms other materials like rubber and standard fabrics by providing a 50% better charge. Participants also share links to resources, including YouTube searches and specific fabric suppliers, to aid in the construction process. Overall, the discussion highlights practical insights and material sourcing for building effective Van de Graaff generators.

TL;DR
Should one spend $250 or try to build one yourself?
Wonder how much skill is needed?

I was hoping to get him to do some research on his own.
 
Unlike some regular folks, the writer of this guide apparently doesn't limit himself to stealing towels (joking here ##-## not calling the helpful person a thief):
from https://www.instructables.com/900000-volt-Van-de-Graaff-Generator-using-cheap-p/:

I tried plastic tape, rubber, fabrics, and the hands down best was a plastic coated fabric used in hotel shower curtains. Its easy to cut and glue and lasts for a long time. The charge it carries was easily 50% better than everything I tried.​

Does anyone suppose that he asked and received permission? I can only imagine the dazed bewilderment of the maid and the houseman encountering the sliced-up remains of the shower curtain ##-##

Could something like that have been a triggering event for Norman Bates?

ok sorry to be anticlimactic ##-## the guy says that you can get the belt material here: https://www.seattlefabrics.com/PVC-coated-vinyl-fabrics_c_65.html#Clear Vinyl Laminated Polyester
