Read the excerpt from "Bone Detective," by Lorraine Jean Hopping. At her lab she mixed the alginate powder with water to form a paste. Standing in front of a mirror, she scooped up a blob and spread it on her tongue. She pressed it down with her fingers to get out any air bubbles. Not bad, she thought. Tastes just like spearmint. She decided to make an extra-thick mold to make it easier to peel off. So, she added another gloopy blog—and another.

With her thickened tongue hanging out, Diane padded around the lab doing odds and ends while the material set. After about 10 minutes, she peeled off the alginate slowly and carefully. It was fragile—bendable and easy to tear—but it made an excellent impression of her tongue.
