Know someone intrigued by the nasty, icky, and disgusting parts of nature? They can enjoy a week uncovering the science behind snot, the bacteria that live in our belly buttons, and gross creatures inside and outside our bodies. Bones and bodies at the Natural History Museum, insect-eating and poisonous plants at the U.S. Botanic Garden spark campers’ curiosity and inspire their experiments and creations. They share their own “Grossology” exhibit at the end of the week.
