I once thought about chosing fluorinated ketone as my presentation topic. Fluorinated ketone with a chemical structure CF3CF2(O)CF(CF3)2 is a colourless and odorless which is fully miscible with water. It has even viscosity similar to water. This chemical product is invented in 2004 by company called 3M and the company named it Novec 1230. What is so special about this liquid like product is when it is in contact with other objects, it doesn't get things wet. For example, I watched demonstration of fluorinated ketone in ''Good Morning America'' and they dunked laptops, cellphones, flat-screen TV's, books, photographs, paintings and clothing in the liquid. All of the electronic devices will work moments afterward or even while submerged.Floating cellphones could still be heard humming tunes and the other items dried within seconds without any of the usual traces of water damage: no marks, smears or smudges.
Fluorinated ketone isn't actually a liquid. It exists as fluid which has charateristics of both liquid and gas. Fluorinated ketone was first introduced as a replacement for halon and fire protection fluid that can extinguish flames without damaging electronic equipment, precious library collections, priceless works of art or any other. When released, fluorinated ketone transforms into a gas that snuffs out blazes. It then evaporates at a rate 25 times quicker than normal water, leaving all other items in the room virtually bone dry. Electronic devices such as laptop did not short out because the fluid is non-conductive (unlike real water). The fact that fluorinated ketone 25 times less energy to evaporate caused the heat of the system to "boil" it off very quickly (boiling point is 49C).
Fluorinated ketone is evironmentally frindely and non-toxic to human at all. May be for those busy people, time of drying body after shower can be saved.
