How was Vita-Wonk finally invented and What was its effect?

Mr. Wonka rolled up his sleeves and began his search for the new recipe. He had to create age, to make people old. So, he set out to search for the oldest raw materials. He took a pint of sap from a 4000-years-old Bristlecone Pine. He tracked down very ancient animals and took little bits from them. After mixing all the items, he did a lot of boiling, babbling and testing into his inventing room. Finally, he was able to invent Vita-Wonk. It was one small cupful of an oily black liquid. Its effect was tested on a young man of twenty. He took four drops of VitaWonk. At once, the young man changed into an old man of seventy-five.
