I spent the better part of the past year writing a novel, in which (among other outlandish incidents) a troublemaking teen attempts to bake a cake with glitter instead of sugar. Now that the book is out, I got to thinking about glitter. What is it made of? When was it invented? Most important of all, what would happen if someone baked it into a cake and ate it?
I thought I knew glitter. I was so wrong.
