Intiñan
Just beyond Mitad del Mundo lies Intiñan, the site that the Geodesic Expedition meant to find but didn't. The highlight here is a small museum with some basic science exhibits illustrating the effects of physics at 0° latitude. In particular, everyone oohs over the demonstrations of an egg balancing on the tip of a nail without falling, and of the north and south drains with clockwise or counterclockwise swirling water. Your admission ticket includes a guided tour in English or Spanish.
