Gabriel's Horn

Hi, I'm Max! 👋

Hi, I'm Max! This golden trumpet has a secret. It starts out wide, then it gets skinnier and skinnier, and it never, ever ends. Now here's the weird part. You could pour in enough paint to fill the whole thing. But you could never get enough paint to coat its wall. That sounds impossible, right? When two true things seem to fight each other like that, we call it a paradox. Spin the horn first. Then try the Paint Race and keep doubling it. After that we'll dive down the throat, past the Moon, until even atoms get stuck. And at the end, I'll show you why this funny trumpet has the same shape as the dent around a black hole. Ready? Grab the horn and give it a spin!
