What is Wonka-Vite?

Wonka-Vite symbolizes the wish of people to become younger. It was a pill made from a variety of fantastical ingredients, like the hoof of a manticore and the trunk (and suitcase) of an elephant. It changed color from yellow to blue and vibrated slightly, as if full of youthful energy. One pill would reduce the recipient's age by 20 years. The old ones took too many and that started the adventure of trying to change them back.
