Hi Tomas, I actually saw some pictures of the whipping and water splashing when researching different Easter traditions around the world, but the pictures I saw are from Slovakia. :) Below is my entry:

It happened to be Easter holiday when I visited some American friends in Atlanta. So I joined some activities with them like the grand family dinner, Mass in a local church, etc.. During the Easter, some kids play games related to the Easter eggs, like egg rolling and egg hunt. Painting eggs is also a fun thing to do. Here are some egg candies I painted with the kids in their family. The Easter egg represents Jesus Christ's resurrection. It's said that to symbolize Jesus Christ's shed blood on the cross, some people dye the eggs red. While in some regions in China, boiled eggs are dyed red as gifts for newlyweds or newborns, which also comes from the fertility and life connotation of the egg.
