Dinosaur egg party favor - Take a balloon and cover it with paper mache.  After it dries, cut a small hole in the top. Take out the old balloon.  Fill it with party favors. I used a small stuffed dinosaur so that it was like hatching a dinosaur. You could use small plastic dinosaurs also.  Seal the whole with newspaper strips and white glue.  I hot glued a pipe cleaner handle to the top. Spray the dinosaur egg with a 3M adhesive. At the party, the kids decorate the egg with precut colored tissue paper squares. When they get home, they get to crack the dinosaur egg open to reveal their party favor.
