Rachel is sitting on the floor, studying her periodic table of elements and trying to find ways of memorizing them individually. Mercury has been memorized in this fashion: Mercury = Hg. Mercury is in the thermometer in the fish tank, but she will substitute the first letters of fish tank with h and g, making it a hish gank. Since Silver is Ag, she has memorized that element as follows A giant SILVER hish.... Most of the elements can be memorized easily enough because they sometimes use the first two letters of their name, but that's not always reliable. And then, of course, there's the Rachel way.
Perhaps, she will find a way of using this giant gold hish to memorize something in her periodic tables.
