Cascarones

Know what they are, or is it just a Mexican thing? Growing up we made them ourselves; now my mom buys them and mails them to me.
This year we had some friends get in on the fun. They had never done this before and had no idea what confetti eggs were. 
It didn't take them long to realize the fun, especially when you bash them on your dad's head. 

I must issue a warning though, sometimes they hurt!!
