Build or Buy a Van de Graaff generator?

In summary, the conversation is about the necessary skill level for creating a Van de Graaff generator. The person has asked for research and others have suggested searching for DIY tutorials on YouTube. The writer of a guide on Instructables has found that the best material for the generator is a plastic-coated fabric used in hotel shower curtains. They also provide a link to where the material can be purchased. The conversation ends with a joke about the potential consequences of using shower curtains for the generator and a reference to the material supplier.

TL;DR Summary
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
