Last year I was planning to do an eggsperiment with eggshells and food dye. Not wanting to boil 100 eggs, I bought these fake white eggs at Walmart because I was sure they'd work great! (They don't dye well at all!) So I had 10 dozen eggshells all in their crates. What do you do with 10 dozen eggshells? Well, they are already lined up in their crates, and they were looking rather periodic.... So my student intern (Emilee) and I started painting them with acrylic paint and voila! A Periodic Table of the Shelliments!
