Building a scale model of our solar system in the desert is an eye-opening exercise

You are no doubt aware that models of our solar system are not to scale. These guys went to Black Rock Desert to create a scale model of our solar system, starting with an Earth the size of a marble. This required seven miles of empty desert to add the other planets (not including Pluto). There's an awful lot of space between these little spheres.
