and what does this things called?

the things that are best fornot conducting electricity are called insulators. some of these materials include rubber, expanded plastics and rubbers...
here's a quote i took from answers.com:
Electrical insulators include rubber, plastic, porcelain, and mica. Thermal insulators. which break up the heat-flow path by absorbing radiant heat, include fiberglass, cork, and rock wool.
if you want, check out the link for yourself....

I'm surprised that so many people haven't mentioned one of the best electrical insulators: Teflon.
There is a property called dielectric breakdown strength, which is the voltage at which the insulator breaks down and becomes a conductor. (When this happens in air, we see a bolt of lightning. If a rubber or plastic coating on a wire breaks down, the result is usually a short circuit, and possibly a fire.)
Look up a table of dielectric breakdown strengths on line; you will see that Teflon is near the top; in other words, it is the best insulator.

Carbon is a great material for stopping the flow of electricity.
Any material that freely allows current to flow is called a conductor,
a material that inhibits the flow of current is called an insulator.

Hydrogen and oxygen would be produced by potential of passing an electric modern-day by using any water. organic water would not habit yet faucet water has impurities besides. you will be able to upload a touch table salt to help.

Probably the first thing most people will think of is dog poop. But also uncooked spaghetti, grapes and copper wire. Wait! I'm not so sure about that last one.

wood,rubber,plastic do not pass electricity through it.these are called non-conductors of electricity

Just the gas mixture in our atmosphere is a pretty good insulator.
