The Museum Of Curiosity

John Lloyd and Anna Ptaszynski are joined by comic and satirist Rosie Holt, theoretical physicist, author and philosopher Carlo Rovelli, and ex-criminal barrister turned pastry chef and author Olivia Potts.

Rosie Holt a classically-trained actor who became a stand-up and famous for her satirical online work which has often fooled intelligent people into thinking she is an actual politician, donates the unwritten second half of Samuel Taylor Coleridge's poem Kubla Khan. She donates it because of the story behind it, with Coleridge being unable to finish it after a visitor from Porlock stopped his flow.

Professor Carlo Rovelli, an Italian theoretical physicist known for his work in quantum gravity, author of multiple books, and philosopher, provides a white hole. This idea behind them is that they are the opposite of a black hole: nothing can ever enter a white hole.

Olivia Potts, a former criminal barrister, who now works a pastry chef, and has written several books including one all about butter, offers a jar of marmalade because it is possibly the most absurd spread around, being made of a bitter fruit.
