Museo de Sitio Intiñan

This open air museum is located approximately 30 kilometres outside Quito, precisely on the equator. Museumguides tell visitors (in English) everything there is to know about the phenomenon equator.
Early indians discovered centuries ago that the equator had special characteristics. They worshipped the sungod Inti by the position of the sun and noticed that on this place their shadows changed for two days a year. These became special holidays that were celebrated on the equator.
Guides also show scientific characteristics of the equator. Gravety is different, you can balance an egg on a nail (for which you receive a nice certificate, free of charge) and water flows differently.
The rest of the museum is dedicated to the indians who once lived here. Replica's of their houses, musical instruments and utensils can be seen and you can try to hit an arrow in a cactus with a three meter long blowpipe.
