Having fun with art on Fridays P (3)
Pre-reading
1. Do you know about these forms of art?
Did you know?
Henna body art is the practice of laying a paste made from henna, which leaves intricate (复杂精细的) patterns on the skin. The paste is left to dry and remains on the skin for some time and then is scraped off (擦除), leaving an orange stain (色斑) that darkens to a final black cherry or coffee colored stain in about 12 hours. The best stains are achieved on the hands and feet, other areas such as the belly, back and chest will stain a lighter color. Henna is different from tattooing in that there is no invasion of the skin with pigment with a needle, it is painless and quite relaxing.

Introduce Pi Day
  Pi Day is celebrated on March, 14th, just like the number that pi is nearly equal to.
  Many scientists work hard to calculate pi, but there is still no end to the number. This makes pi puzzling, even for the most famous scientists and mathematicians. I am also deeply attracted by its mystery.
   Pi Day is about having fun with the number. People celebrate Pi Day by eating or throwing pie and with fun pi-related games and activities. Einstein’s birthday is also on this day. Isn’t it amazing?
