"Never mind," Snape said when he saw the time, "you'll be brewing the potion that's on the parchment on your desk, and then you'll have to name it, get started.
Everyone started gathering ingredients and following the directions on their parchment.
When everyone was done Snape went around asking the students what their potions were.
"It's a mild energy potion," Hermione answered when Snape got to her.
"Gatorade?" Harry asked.
"Nope, it doesn't really have a name," Hermione answered.
"And what is yours, Potter?" Snape asked.
"It's name is," Harry paused, "Bob, Bob Potion, and he's a shrinking solution."
Snape opened his mouth, but closed it when he realized that Harry knew what he had brewed.
"Mine's hot," Ron announced, "and it's a forgetfulness potion."
