Mr. Wynn was wearing his huge safety goggles that make his eyes look like two giant watermelons, and he told us to stand back. He was trying to do this "Elephant Toothpaste" experiment where foam shoots out of a tube. He goes, "Okay guys, watch the pressure build," and then he poured the last ingredient in. Instead of a cool fountain, the top of the bottle literally popped off like a rocket! Foam sprayed everywhere—mostly on Mr. Wynn’s shoes and the ceiling. He just stood there looking like a snowman while the whole class started dying laughing. I thought he’d be mad, but he just wiped a blob of foam off his nose, tasted it (which was gross), and said, "Well, I guess that’s one way to clean the floor." He’s definitely the chillest teacher I have.
