Snowmakers turn water into tiny droplets, which then freeze and fall as snow.
Water is one of the most common substances on the planet.
And it has some interesting properties which are key to the snowmaking process. Water is a liquid, which means it can't be compressed. When we attempt to do so, it will always go from the area of highest pressure to the area of lowest pressure it can find. So if you put pressure behind water with a pump, you'll move it as long as you've provided a place for it to go. That's important, because the water reservoirs snowmakers draw upon are often miles away from the trails where they want to make the snow.
