You know how in cartoons snowballs can roll down hills and pick up more and more snow until they’re a big snowball? Or how cartoon kids roll balls of snow to make bigger balls of snow to make snowmen? Does snow really work like that??? Does that happen in real life???

I’m not sure why you’re asking me, specifically, but… yes? It doesn’t always work – the snow needs to be a specific texture and temperature to stick. A heavy blanket of freshly-fallen snow works best, preferably early in the season when it’s below freezing but not hellishly cold. It makes a bizarrely satisfying rumbling noise as you push the ball of snow further and it grows larger and larger until you can’t push it any further. It’s one of the sweetest pleasures in life.

It doesn’t work as beautifully as in cartoons, but snow does tend to stick to itself when it’s not really powdery, so you can absolutely do that.
