George's Marvellous Medicine

George hated his grandmother. She was a selfish, nasty, grumpy old woman. Was she a witch?
Then, one day, George has a marvellous idea. He makes Grandma a magic medicine from all the runny, powdery and gooey things in the house.
“Perhaps she’ll become a better person, or her head will explode!” he thought.
Open your mouth wide Grandma, you are going to have a nasty surprise!
