Aunt Amy's egg hunt

My step-sister Amy has the coolest way of doing an egg hunt. I thought I'd relay it.
She made more than 100 eggs. She dyes real eggs (not sure whether she cooks them or not...I'll find out) and cracks off the tops and emptys them. Then she puts a coin in and seals the top with tissue paper and a little water. Then the Great Egg Hunt!
After the kids have gathered the eggs, they all troop out to the driveway and stomp on their eggs to get the coins out! What fun! Flash made 52 cents, although we had to tell him to pick up the shiny things.
My only worry?
That he'll start stomping on our eggs right out of the fridge.
