You may have seen Richard Browning’s Iron Man suit in the news or watched our video about the world’s Smallest fidget spinner, but do you know the science behind these game-changing inventions?

To celebrate our new Guinness World Records: Science & Stuff book, we’ve put together a video that explains how some of these record-breaking creations came about.

Fastest speed in a body controlled jet engine powered suit

British inventor and ex-Royal Marine, Richard Browning, has created the closest thing to Tony Stark’s Iron Man suit ever seen to date.

His Daedalus suit comprises six micro gas turbines, which helped him achieve a speed of 32.02 mph (51.53 km/h).

Richard is constantly enhancing his record-breaking suit and plans to add new features such as auto-balancing, 3D-printed metal mounts and even LCD screens to it can be made invisible!

Most backflips with a water powered jetpack in one minute

Aquatic jetpacks don’t use fire, they gain thrust by sucking up water under high pressure then redirecting it downwards.

The Most backflips with a water jet pack in one minute is 29 and was achieved by Liu He (China) in Xi'an, Shaanxi, China, on 10 October 2016.

First prosthetic limb based on a videogame

Daniel Melville (UK) owns and wears a copy of the arm worn by Adam Jensen in Deus Ex, Square Enix's cyberpunk RPGs videogame series set in a futuristic era of transhumanist body upgrades.

Conceived in April 2015 and completed on 1 June 2016, the "Jensen arm" has been created by the UK company Open Bionics and is a 3D-printed limb which took one month to go from rendering to being made wearable.

"The control system in the arms, and the way they operate, is the standard control system that you'll find in other bionics. However, the unique thing about our arms is that they're stylized – they come from the world of sci-fi, whether that's Deus Ex, Star Wars or Marvel. They're completely 3D-printed and we can make them very small for children. After Dan's arm, we built a smaller Jensen arm for a 10-year-old girl in the UK called Tilly," Open Bionics co-founder, Samantha Payne.

Smallest fidget spinner

Measuring at just 5.09 mm (0.20 in) long, MinebeaMitsumi Inc. from Minato, Tokyo, has built the world’s Smallest fidget spinner.

Built using MinebeaMitsumi Inc's existing record-breaking product, the Smallest commercially available steel ball bearing which itself is a mere 1.499 mm, the spinner weighs a feather-lite 0.027 g (0.00095 oz).

The Guinness World Records: Science & Stuff book delves deeper into record-breaking creations and their inventors, including features on 3D printing, electric supercars and the world’s Fastest toilet.
