Avalanche effect

Avalanche effect is like a snowball rolling down a hill. If a tiny snowball (like a tiny rock) starts rolling down a hill, it will get bigger and bigger as more and more snow and dirt get stuck to it. Eventually, it will turn into a huge snowball (a huge mass of snow). The avalanche effect is the same thing, but instead of a snowball, it is ideas, concepts or thoughts. When one idea or thought starts rolling down the hill, more and more ideas and thoughts get stuck to it and it grows bigger and bigger until it becomes a huge mass of ideas.
