Closely-guarded secrets to David Copperfield's magic tricks have been accidentally dumped on the surface of the moon after a failed mission by an Israeli firm.
They are among a record of mankind's greatest achievements currently sitting somewhere on the lunar surface after a failed attempt to land a probe, experts say.
Israel was unsuccessful last week in its attempt to become the first country to land a private spacecraft on our natural satellite.
Space IL's Beresheet spacecraft, however, was carrying a library containing all of Wikipedia as well as 30,000 books and guides to 5,000 languages.
Alongside the Bible and an Israeli time capsule, some of the quirkier items aboard were David Copperfield's magic secrets and a recipe for queso - a cheese based Tex-Mex appetiser - provided by a cafe in Texas.
The craft itself was destroyed in the attempt, but the creators of the Lunar Library - which was designed to be indestructible - say it might have survived.
They are calling on the public to help them track down the possible impact site of the library after the aborted landing.

Beresheet stood around five feet (1m) tall and 7.5 feet (2.3m) wide with its landing gear and legs deployed
The probe stayed in Earth's orbit for a month before slowly widening its ellipse until its farthest point from the planet, at nearly 250,000 miles (400,000km) away.
Beresheet was then slowly introduced to the orbit of the moon.
It was intended to be first private craft to land on the lunar surface, where it was designed to operate for just two days.
On April 11, 2019, however, Space IL - the firm behind the project - announced that the craft began to break apart just nine miles (15km) from the surface.
The 'Lunar Library' was created by the Arch Mission Foundation, based in LA, for the purpose of preserving humanity's 'precious knowledge and biological heritage' well into the future.
The library contains 25 nickel film disks, which resemble tiny DVDs around half the thickness of a human hair.
Each disk is made up of multiple layers of information, the first four of which are comprised of up to 60,000 photographs of pages of books, photos, illustrations and documents.
'We have either installed the first library on the moon or we have installed the first archaeological ruins of early human attempts to build a library on the moon,' Arch Mission co-founder Nova Spivack told Mashable.
'When you look at the Moon from now on, realize there is a lost library there containing Wikipedia, 30,000 books, 5,000 languages, and the history of the world.'
Arch Mission has created a Google document that details all of the technical specifications of the Lunar Library.
It also compiles all of the data of the crash, gathered by SpaceIL, the Israeli nonprofit
