Although the origins of Songkran are far more religious, splashing complete strangers with water has become the main attraction of the festival. Dousing or sprinkling people with water signifies the washing away of bad thoughts and actions, and brings them good luck in the new year.
As a procession and formalities end, a throng forms in the street to dance, party, and throw water in good-natured fun. To up the ante, many Thais add ice to their water or travel in teams that wear masks and carry large water cannons. You probably won't mind the drenching; afternoon temperatures in April regularly rise above 100 degrees Fahrenheit.
