Bob's sweet secretary sent home a big Easter basket for Claire. One of the things in it was so neat. I have never seen these before. Have you?
They are real egg shells that have been emptied and filled with paper confetti. The top is gone and covered with tissue paper that is dyed the same color as the egg shell.
Then you throw them in the air and let them smash on the sidewalk. It's very satisifying. :)
