Los Cascarones is a tradition celebrated in Mexico, Spain, and throughout the Southwestern part of the U.S. It is celebrated around Easter - some do the actual "egg-breaking" on Mardi Gras and some wait until Easter Sunday. It is a very educational lesson making the students more aware of a tradition that most haven't heard of. It is a custom that was started with the travels of Marco Polo to China where many think it orginated and then back with him to Queen Carlotta who liked the cascarones so much that she took the custom of the eggs to Mexico with Maximillian during his reign there. Thereby, becoming a custom celebrated in the Americas.
