Parque das Nações, Lisbon
Piso escorregadio ("Slippery Floor")
This fountain is part of the "water park" area of the Parque das Nações (Expo) area of Lisbon. To the right there are pools with stepping stone pathways, interactive science "toys" that fascinate, and some wonderfully cool, shady areas.
A few minutes before I took this picture there was a maintenance van parked beneath it, which gives an idea of how big it is.
Tomorrow's picture is a view from beneath the jets of water.
