Man, that looks like a lot of fun! I would ride this playground slide, which is somewhere in Japan, but only once unless I could drive back up the hill. -via College Humor

Two Dutch architects want to alter the storm drainage system of the city of Rotterdam to redirect water into playgrounds. The water will be used to fill fanciful ponds and moats for children to play in/around:
In Florian Boer and Marco Vermeulen’s proposal, rainwater runoff isn’t funneled into a complex system of underground pipes, a system that is rather expensive to build and maintain, but is managed instead through a network of surface reservoirs, the Waterpleinen, or Watersquares. These storage spaces will be dry for most of the year, but during storm events, they will collect water from the surrounding neighborhood. If one reaches capacity, excess water will overflow into another basin. After the rain, the collected water will slowly recede into nearby bodies of water or seep into the soil.
So instead of being buried in concrete, excised from the daily life of the city and only experienced by municipal workers, urban hydrology is visibly, even prominently, incorporated into the surface fabric of the city. Programmed with recreational opportunities when its dry and even while inundated, its infrastructure provides active public spaces for the local area, not dark playgrounds for a handful of urban explorers. It even becomes an event, its frolicking rivulets and interior lakes staged for the young and old.

The blog Funster Mental Floss has pictures of ten amazing playgrounds from around the world. Pictured above is the St. Kilda Adventure Playground in Port Philip, Australia. It covers four hectares of land and includes a beached pirate shipwreck and a submarine. It was built after World War II to help disadvantaged children in the area develop mentally and physically.

UPDATE 9/16/09: In the comments, Miss Cellania says that Funster copied the work of Mental Floss writer David K. Israel, so I have altered the link. Thanks for pointing this out, Miss C.

Sculptor Tom Otterness created this amazing bronze tin man jungle gym as a private commission. That’s one lucky kid who has his or her own Otterness creation as a playground! Link – via Super Punch
