It's Frankenstein time. Who doesn't enjoy the smell of ozone and the snap of a big fat spark?
The dome is rotating due to vibration
Although a Van De Graff generator has recently been posted I decided to post mine based on it's substantial differences.

Sooooo useful.
I noticed corona discharges at the center edges of the dome on the video above. Corona points are electrical charge dissipations that decrease a VDG’s potential output. To reduce this phenomenon you should smooth out and round off any acute edges and or angles. The more round and seamless the dome is, higher the output. Just a tip!
do you have any ideas of maybe why it does not work??????? or what i can do to make it work ?????

sheial360 : Make sure that the Bottom brush side has a good earth ground connection. If you’re using a 120V motor to turn the roller look for the Green wire on the motor power cord (make sure you unplug the motor first) it’s usually located in the electrical termination enclosure or motor housing and connected to a terminal post. This wire is used as a fail safe wire just incase the motor were to short, but it also serves as a good grounding point which runs to the earth ground for your house. Use a fork or ring connector with the right Gauge aka “AWG” size to make the connection, and be sure to crimp the connector properly. I wouldn’t recommend grounding to another spot on the frame, due to higher resistance, unless the frame is made of copper or silver, which is highly unlikely. OR you can stake a 5 to 6 piece of copper pipe or rod into the ground, leaving about 6 inches sticking out to tie in your ground ( if you do this make sure you use a copper ground clamp when connecting your wire.) Also you need to consider Humidity, it’s harder to produce sparks in humid atmospheres. Running your VDG indoors with the AC on might help. Also instead of using panty hose, try using a surgical rubber tourniquet or tube for the band ( Split the tube down the middle with a razor evenly) sand the ends down to a taper apply rubber cement to the ends, overlap them and press together. Lay the glued ends on a flat surface and lay a heavy book or heavy flat object on the glued ends to help seal them together (make sure you wipe away any excess beforehand to keep the band from sticking to the other surfaces) and just wait until the bonding process is complete. I hope this helps you!And does the sock have to move or does it stay still ????
The sock must also move, just like a fan belt on a car
Let me make this clear, you will probably get a very nasty jolt of mains supply electricity, with chances of it killing you. No joke, do not attempt this!!!!!!!!!!!
Presuming you've insulated the other wires coming from the plug properly and presuming your house wiring is correct and to code* you should be fine using the ground pin in your outlet.
* use an outlet tester. always. every time. before you plug anything over 1000W(commercially produced) or home-made into an outlet. most wiring is shoddy, incorrect, or just not safe. better to be safe than sorry.
