Visit the history channel to research the significance of St. patrick's day and how people celebrate this holiday across the country and around the world. Did you know that the Chicago River is died green for this special day? According to the history channel "The practice started in 1962, when city pollution-control workers used dyes to trace illegal sewage discharges and realized that the green dye might provide a unique way to celebrate the holiday. That year, they released 100 pounds of green vegetable dye into the river--enough to keep it green for a week! Today, in order to minimize environmental damage, only 40 pounds of dye are used, and the river turns green for only several hours."
