George's Marvellous Medicine: Level 5

🔖 George hates his grandmother. She is a selfish, nasty, old woman. Is she a witch?
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 thinks.
Open your mouth wide Grandma, you are going to have a nasty surprise!
