Guinness World Records Day: From biscuit dunking bungee jumpers to skydiving magicians and the shortest married couple

A bungee jumper who dunked a biscuit in a cup of tea after diving from a height of 246ft (75m) and a magician who performed 11 tricks in a single skydive, are being joined by 600,000 other people around the globe who are attempting to make history on Guinness World Records Day.

Armed with a Chocolate Hobnob, Simon Harris dived from a height equivalent to 22 storeys to successfully dunk his sweet treat in a cup of tea emblazoned with the Union Flag.

The 24-year-old's technique involved clasping one wrist over the other to offer greater stability and precision as the snack surged towards its target.

Speaking after his feat in Bray, Berkshire, Mr Harris said: "It was pretty difficult. Going down and having to nail that cup of tea was pretty tricky.

"(It was) absolutely incredible - the feeling in my chest and seeing everyone's smiles, it was fantastic."

Also with a head for heights was magician Martin Rees, 28, from Hemel Hempstead, who performed a record-breaking 11 tricks in a single skydive.

Other Britons who made it into the record books were people who wowed judges with their record-breaking ability to identify Queen songs, comic book superheroes and Oscar winners against the clock.

Measuring in at a combined height of 70inches (1.78m) Paulo Gabriel da Silva Barros and Katyucia Lie Hoshino Barros from Brazil were crowned the world's shortest married couple.

The pair met eight years ago after meeting on social media.

While in the USA the Harlem Globetrotters went for numerous record attempts.
