Why does this YouTuber ALWAYS go viral?

this YouTube channel goes viral with nearly every video they make even though they talk about things you would probably have found boring at school but how well there's three things in particular they do that you might not expect the first is they make videos about weird questions people always ask themselves like what does happen if you drop a penny from a skyscraper which creates an irresistible urge for people to click next they always focus on making

fun doesn't titles that make their viewers curious I mean look at this once upon a time this video was called The Strange application of the Magnus effect and it did rubbish but when they changed the title to this it made the viewers curious and got millions of views and finally there's a pattern you'll see on their channel that helps them get millions of views and that is they make videos about the world's largest roundest or heaviest

items which once again makes the viewers really want to learn what they might be and the fourth bonus thing they do is subscribe
