post something interesting, (not guiness world records) something sciency.

Show your knowledge or seek answers.

my physics fact is: Plasma (in one form) is ionized gas, heated to thousands of degrees. In future space exploration plasma thrusters are planned to be used as it is more efficient and faster. prototype's have been designed with electro-magnetic coils to direct the flame as plasma vaporizes any matter it touches.

your turn! :D
