It's a Boy Thing

Slimy, gooey, gross. That's what the summer camp was called that Marcus attended. He came home with a bag of green silly putty he affectionately called "snot." It was a day filled with science cleverly disguised by discussing burps, ear wax, and other gross things. He loved it.
Whatever works.
Next week's camp is called "Enchanted Garden Fairies." It's safe to assume he won't be going to that one.
