Cork does not have the "free electrons" that are necassary for current flow. In other words, cork holds onto its electrons better than an object such as metal does.

Cork can be used in a lot of ways. Because it floats a magnetized needle placed on top of a piece of cork will act as a compass. This simple device can also respond to a permanent magnet and show action at a distance. Cork can also be used to seal a flask against low pressure leakage.

Yes, but very slowly. Cork is a good insulator.
It's an insulator - it's manufactured from tree bark.
A material that insulates, especially a nonconductor of sound, heat, or electricity. A device that insulates another material or space from something. For instance glass is a good insulator from electricity. The electrons will not flow through glass. Cork is a good insulator from sound. Sound waves have a hard time passing through cork. Wood is a good insulator from heat.

Cork should be a poor conductor. Cork is a lite wood like, low density material. Often used to insulate heat, which is a clue. Things that are not good conductors of heat are normally poor conductors of electricity.
