This one is called " The Gum & Cracker Game "  I used to play this at all of my birthday parties growing up, and now that I have a child of my own I thought this would be fun for her and her friends to learn too. You need to get a box of saltines and enough gum for each child to have 1 piece, first you have them put the cracker in their mouth ( no chewing ) then you have them put the piece of gum in their mouth, then start chewing, the goal is whomever can blow a bubble first is the winner.  This is always amusing for others to watch!!!
