FTF: Fledermaus
First: The junior high chemistry lesson:
Lithium was discovered in the mineral petalite (LiAl(Si2O5)2) by
Johann August Arfvedson in 1817. It was first isolated by William
Thomas Brande and Sir Humphrey Davy through the electrolysis of
lithium oxide (Li2O). Today, larger amounts of the metal are
obtained through the electrolysis of lithium chloride (LiCl).
Lithium is not found free in nature and makes up only 0.0007% of
the earth's crust.
Many uses have been found for lithium and its compounds. Lithium
has the highest specific heat of any solid element and is used in
heat transfer applications. It is used to make special glasses and
ceramics, including the Mount Palomar telescope's 200 inch mirror.
Lithium is the lightest known metal and can be alloyed with
aluminium, copper, manganese, and cadmium to make strong,
lightweight metals for aircraft. Lithium hydroxide (LiOH) is used
to remove carbon dioxide from the atmosphere of spacecraft. Lithium
stearate (LiC18H35O2) is used as a general purpose and high
temperature lubricant. Lithium carbonate (Li2CO3) is used as a drug
to treat manic depression disorder.
Lithium reacts with water, but not as violently as sodium.
No puzzles here; the cache is is fairly easy to get to. The park
is a high muggle area, so some discretion is needed.
*** I originally had an EPE of 39 feet when I placed this. I have
updated the coordinates with a strong WAAS signal as of 2 Jul 2005.
Hope that helps. ***
