Build a Van De Graaff Generator

can i suggest you use a kitchen bowl upside down insted of a coke can

do you just use the glass from the christmas light or he whole bulb if u did just use the glass how did u get it off

Yep, it is just the glass. You bend the wires down and the bulb will come out of the holder.

thx

does the light bulb on the top spin?

Yes, it is the top roller.

i hate you takamine2813

I was trying to made one van de graaff generator in my home but it does not work. The upper roller is made of rubber and lower is made of metal (it's drives by the engine from the drill). As a rubber belt i"ve got the innertube from bike. the lower comb is attached to the gdound and the upper comb to hollow sphere. Help me please!!!

Electrostatic machines are a pain. I am not sure that metal and rubber are the best to use. I don't think I can help you much without knowing more.
