And the earth’s still here, the sun’s still here, the moon’s still here.” -John Ellis

It was also one of the most disputed, with hundreds of scientists refusing to accept it. Yet with less than $100 and a single day’s worth of labor, there’s a way you can prove it to yourself: by building a cloud chamber.
