The subject of science can sometimes be quite difficult – but it doesn’t always have to be!

Expert Science Bob, who is featured in the pages of our new book, Science & Stuff, has found a way to simplify some of our most complex records attempts to show you the individual elements that go into record-breaking.

Below he analyses what's behind one of our most popular records, the Fastest speed in a body controlled jet engine power suit, which was set for Guinness World Records Day in 2017.

The name of this title can sound intricate but is essentially measuring how fast someone can fly in their Iron Man-like invention with the current record at 32.02 mph (51.53 km/h).

Speaking at the time of setting the record, inventor Richard Browning (UK) explained some of the thinking involved in creating his record-holding suit and what one of the most challenging aspects was.

"In hindsight it looks easy, but it was actually arriving at the layout of engines we’ve got. You look at it now and think ‘that’s obvious’ but it wasn’t. Even as simple as holding your arm out, should you have one here [points to one side of his wrist] or here [points to the other side]? Should you have four engines? Three engines? How should they be spread, should they be higher on your arm?" Richard Browning.

Many gathered to watch kerosene-fuelled micro gas turbines, but how does it actually work?

Well for a start, as Science Bob explains in more detail, they're actual jet engines attached to the arms which Richard Browning used to not only hover but decide on his direction of travel and reach his record-setting speed.
