Snowball

I'm sure everyone's heard of the snowball effect right? Where a teeny weeny little bit of snow can roll down a hill, piling up more and more snow around it as it makes it way down and by the time you realise whats going on, its too late – you don't even know what hit you.

I've never actually “seen” one happen (with real snow, I mean). But today, I experienced what it must feel like, to get hit by a snowball that you last saw as a miniscule pebble.
