Geocache Description:

One of the caches in the ChemCache IIIA: Whistogens (GC11J4D) Series. Get the code to solve the puzzle!

This is another one of the Chem Caches - This one is part of the unknown cache series ChemCache IIIA: Whistogens. It is the only metal, except for mercury, caesium, and rubidium, which can be liquid near room temperatures; this makes possible its use in high-temperature thermometers. It has one of the longest liquid ranges of any metal and has a low vapour pressure even at high temperatures. Ultra-pure gallium has a beautiful, silvery appearance, and the solid metal exhibits a conchoidal fracture similar to glass. The metal expands on solidifying; therefore, it should not be stored in glass or metal containers, as they may break as the metal solidifies. High-purity gallium is attacked only slowly by mineral acids. Gallium arsenide is capable of converting electricity directly into coherent light and gallium arsenide is a key component of LEDs (light emitting diodes). [from www.webelements.com]
