eaglebtc writes "Tuesday on Good Morning America, a representative from Tyco Fire & Security demonstrated an amazing new substance called Sapphire: a water-like fluid that does not get things wet. He filled a small fish tank with Sapphire and submerged a book, a laptop, and a flat panel TV. Both electronics were turned on when submerged; all three items came out completely unharmed. Click here for a slideshow of the demonstration. The official name for Sapphire is actually Novec 1230. Read about it here (PDF). Tyco sees practical applications of Sapphire in fire extinguisher systems for museums and libraries. By the same token of practicality, regular readers of Slashdot probably have something else in mind: total-immersion watercooling. Just think of the possibilities!"
