How I would make Confetti Eggs (Cascarones) in 10 seconds, Not Really

Easter is a Christian holiday that celebrates the resurrection of Jesus Christ. In southwestern United States, they like to crack eggs on top people on this day. Not this kind of egg, but this. These kinds of eggs are called Cascarones.
The Prep:
Taking a regular chicken egg, poke a hole to empty the contents. Rinse and boil the eggshells, Submerge them into food coloring, let them dry then fill the eggs with some confetti, glue the opening with tissue paper.
The Game:
The Cascarones are scattered throughout the backyard with normal easter eggs which are filled with candies and money. But we also put something else in our easter eggs. Then let your friends hunt for them. Once collected, kindly crack the eggs on others' heads and let the confetti land on their hair.
