You might recognise this guy from his YouTube channel “Ryan ToysReview”.
The American kid is one of the youngest people to enter the Guinness World Records 2018 book.
Aged six years old, Ryan stars in the Most viewed YouTube channel for a "millennial" (someone born post-2000).*
As of 4 May 2017, "Ryan ToysReview" had been viewed an incredible 12,076,126,791 times since the first video was posted in 2015.
Ryan uploads videos of himself (or his family) playing with toys or games and assessing them.
How did this all come about? "When Ryan was younger, he would watch kid YouTubers and say he wanted to film videos just like them," said his mum.
"Our favourite type of videos to film are science experiments," she added. "For example, in one video we created elephant toothpaste to show an exothermic reaction. We especially enjoy these types of videos because Ryan is learning science while still having fun and teaching other kids."
Ryan is a record-breaking YouTuber at the moment but ‘when he grows up’ he would like to drive a garbage truck or be a singer or a police officer.
What’s next for Ryan and his family? "Breaking the world record for most whoopee cushions sat on in 30 seconds sounds like a blast!" says mum.
