So far, nothing had happened. “Looks like it’s safe,” Zoe said. “Wait,” Bryan said. “Are you sure?” “As sure as I can be,” Zoe said, taking off her boots. “It’s not like I have my lab here to test it. But it hasn’t disintegrated the tree branch. That’s an improvement over the last lake.” Zoe put her hands into the water. It was cool and refreshing against her skin. She splashed it over her arms and shoulders. The others stood there watching, like starving men before a banquet. “Aren’t you going to wash?” Zoe said. Cassie and Aaron headed a little farther down before entering. “Don’t go in too deep,” Bryan said. “I won’t,” Cassie said, rolling her eyes. Zoe took off her top, wearing just her bra. She washed all the gunk and dirt and sweat off her body.
