Thompson was known on YouTube as “The King of Random,” which was his science-themed YouTube channel with more than 11 million subscribers.
He created videos of experiments and how-to science tips that have been watched more than one billion times.
Thompson made headlines last year after complaints about explosive noises in his suburban Salt Lake City backyard brought criminal charges.
The YouTuber later agreed to make safety-themed videos in a plea deal that would have wiped his record clean.
