This is incredible (and incredibly nerdy). Wylie Overstreet and Alex Gorosh have built the first scale model of the solar system in the form of a beautiful time-lapse. They used an Earth the size of a marble, and a sun the size of a big reflector disc, measuring out the various planetary orbits in the middle of Black Rock Desert in Nevada. At night, they used their cars to drive the orbits of each planet with a different colour lightbulb.
