Hey guys,
I chose WHIRLPOOL as my W assignment. I found some videos, you can visit these sites if you wish to see the videos.
This video is short:

XENON
For my X assignment I did Xenon
WHAT IS XENON?
Xenon is a chemical element represented by the symbol XE. Its atomic number is 54 and is colorless, heavy but also odorless. In group 18 (VII) of the periodic table, xenon is said to be one of the noble gasses. Xenon’s atomic weight is 131.3.
WHAT IS XENON'S HISTORY?
Xenon was discovered in July 12, 1898 by the British chemists Sir William Ramsay and
Morris Travers. It was formerly believed to be chemically inert, but since 1962 several compounds of xenon have been prepared.
Ramsay suggested the name xenon for his gas from the Greek word ξένον meaning “foreign” or “strange”.
In 1902, Ramsay estimated the proportion of xenon in the Earth's atmosphere as one part in 20 million.
Xenon is present in the Earth’s atmosphere in minute amounts.
Xenon melts at -111.8° C (-169.2° F) and boils at -108.1°c (-162.6° F). Xenon can undergo a few chemical reactions such as the formation of xenon hexafluoroplatinate, the first noble gas to be synthesized.
During the 1930s, engineer Harold Edgerton began exploring strobe light technology for high speed photography. This led him to the invention of the Xenon flash lamp in which light is generated by sending a brief electrical current through a tube filled with xenon gas. In 1934, Edgerton was able to generate flashes as brief as one microsecond with this method.
WHAT ARE ITS USES?
Xenon is used principally in such lighting devices as high-speed photographic tubes. Xenon can also be used in game consoles. Microsoft's Xbox 360 confirmed that they had used some xenon on the console. Projectors also contain xenon.
In Russia xenon was in anesthesia, hopefully a doctor had safely operated at 2 patients.
