Snow. Every kid has taken a bite of snow, but thousands of people die every year in snowstorms. Watch out for photokeratitis, otherwise known as snow blindness. And if you’re exposed to snow for too long, you can lose limbs to frostbite. Just an inch or two of snow makes them treacherous.

A recent snowfall makes the world white, and kids love to build snowmen, snow forts and have snowball fights. Some people live in igloos, built out of snow.
