I eat kaolin clay and chalk.I like Prang chalk and roseart. Crayola has a nasty taste. I like a cup of water with diatomaceous earth mixed in. Has the consistency of milk but taste like dirt. I like that yummy chalk like dirt flavor. It feels satisfying to eat. Like the feeling a fat lady gets from pizza and cake, I get from chalk and clay. The crunch is better than pretzels and chips.
