The Kid Should See This

What happens when you pour ball pit balls onto an escalator?

They bounce down, they’re carried up, they bounce down, they’re carried up… how long can this go on?! This is what happens when someone pours a huge bag of ball pit balls onto an escalator. (P.S. kiddos, it’s best not to play on escalators, but you know, since these guys did, let’s watch.)

There’s more physics ball fun to watch: Liquid Nitrogen & 1500 Ping Pong Balls and 2,000 ping pong balls & 30 middle-school teachers in Zero G.
