Prayer flags are rectangular pieces of cloths usually strung in the Himalayas. Traditionally, prayer flags come in sets of five: one in each of five colors. The five colors are arranged from left to right in a specific order: blue, white, red, green, and yellow. Blue symbolizes the sky and space, white symbolizes the air and wind, red symbolizes fire, green symbolizes water, and yellow symbolizes earth. Traditionally, prayer flags are used to promote peace, compassion, strength, and wisdom. The students at Towey created their own prayer flags for the upcoming Earth Day. They each made a flag with a picture of their own creation, and then attached them together on a string to hang up.
