Button mushroom: Agaricus bisporus, these mushrooms were first cultivated in France in 1650. Today they are among the most commonly consumed mushrooms in the world, and are grown in over 70 countries. The mushroom is not a plant, it is a fungus, one of the major differences between the two, is that fungi have chitin in their cell walls, whereas plants have cellulose in theirs. Chitin is also found in exoskeletons of arthropods such as spiders, crabs, shrimp, etc. On average, Americans eat 4 lbs. of mushrooms per person each year.

Nail Polish: The coloring of ones nails can be traced back to ancient Egypt, where nail color signified social status, red being royal, (the color red was mostly derived from henna, or even blood) whereas women of lower rank were allowed to use only pale hues. The next major step in the evolution of nail polish took place in China around 600 BC. Chinese royalty used gold and silver, along with black and red nail lacquer that was made using Arabic gum, egg whites gelatin and beeswax Modern nail polish became readily available in the 1920’s, when automobile paint was created.
