Thursday 9 November is Guinness World Records Day 2017 and incredible record attempts have been taking place all around the world in honour of the special occasion!
Check out our live blog to find out about all the amazing action from the day, but we've made a short list of some of the best records below - including a real life 'Iron Man' and a cake that weighs as much as an elephant...
Most Risley flips in 30 seconds
You might not know what a Risley flip is (yet), but it's definitely an impressive performance! Extreme gymnasts Fabio and Giuliano Anastasini (USA) achieved a record-breaking 32 flips. Watch theirr attempt in the video below.
Fastest speed in a body controlled jet engine powered suit
Technology company founder, Richard Browning has created a machine that turns normal people into superheroes. Soaring above a lake at Lagoona Park in Reading, UK, Richard managed to reach a speed of 32.02 mph (51.53 km/h)!
Largest vegan cake
This semolina cake weighs more than a bull elephant. (Well, it did before it was all gobbled up.) It was baked by Swedish YouTuber Therese Lindgren and friends in honour of GWR Day 2017.
If something is vegan it contains no animal products at all. The recipe for success included 44.5 kg sugar, 3.56 kg flour, 62.3 kg semolina and 89 kg soya yoghurt. The cake was then topped with 26.7 kg whipped soy cream and 35.6 kg strawberries – among many other ingredients.
Largest hoop spun
It's tricky enough just spinning a regular-sized hula hoop, so imagine how hard it would be to spin a 5.14 m (16 ft 10 in) aluminium hoop! That's what Yuya 'Hoop Man' Yamada did to earn his place in the record books for GWR Day.
