Let me know if you spot any significant mistakes! - PS And I'll admit one correction right now: the titles claims 22 YouTubers but Ayliean is mainly a TikToker; Hannah Fry doesn't have her own channel and nor does Eugénie. But they all do loads of work on, in and with YouTube videos! Filming of each clip was done by whoever is in the shot. Editing by Alex Genn-Bash. It has aged him 22 years. Stupid idea by Matt Parker with help from Steve Mould and Grant Sanderson. Music by Howard Carter Design by Simon Wright and Adam Robinson English subtitles thanks to the world's greatest team of volunteers.
