A picture tube is an insulator. The electrons would gather up and so, create an electric charge when the TV is on. If it was a conductor, the charge would not build up.
Hope this helps :)
Glass is an insulator, as it DOES NOT conduct current. It is a material which has no free electrons available to flow as electrical current. Conductors, like copper or aluminum, have free electrons, or electrons in the outer shells of their atoms that are easily knocked loose. These electrons flow from negative to positive when an electrical potential (voltage) is applied across the material. We call the flow of electrons "current".
Electricity is electrons moving through a conductor like copper and creating a current. So no it does not create light unless you rune the electricity through a florescent tube.
another name for test tube is culture tube or sample tube
tube light
red tube
It is a insulator. The glass does not have free electrons to flow as current, and the air in the tube is also an insulator.

A rubber tube is an insulator because it does not conduct electricity. Rubber is an electrical insulator due to its high resistance to the flow of electric current.
Gum rubber is typically considered an insulator because it is a poor conductor of electricity. It does not allow electricity to pass through it easily.
Glass in a molten state is a conductor of electricity. When glass turns to a solid state it becomes an insulator.Basically, glass in a window or a test tube would be the solid state and so it is a insulator of electricity.

There are definitely elastic resistors. The only application I can think of at this moment is the elastic sensor wrapped around a person's chest and used to monitor his breathing during a sleep study or a polygraph test. If you're talking about the common "rubber band" typically used to hold a bunch of papers or a wad of cash together, then no, that particular material is not too good at conducting a current.
A picture tube is that big glass thing you look at that the picture appears on. The back of it has a regular tube socket.

Those were picture-tube TVs. The picture tube was almost as long as the TV screen was wide.
Aerogel is the best insulator [.004 W /( MK)] and diamond or diamond-chickenwire-tube (carbon nanotubes) are the best [2320 W/(MK)]. See: http://en.wikipedia.org/wiki/Thermal_conductor http://www.unitednuclear.com/aerogel.htm
It shouldn't. If there is no actual power to the CRT (no picture visible) then there really can't be any degradation of the tube.
