New York Street Games is a 2010 documentary film directed by Matt Levy about childrens games played by kids in New York City for centuries. The games are fondly remembered by people who grew up in the city. Current and historical documentary footage shows children playing these games, interspersed with scenes of celebrities discussing their own childhood experiences playing these games on the streets of New York. The story is brought to the present with discussions of the current role of street games and opinions as to what kids lose by not having the freedom to play without adult supervision, most importantly the social skills developed when kids could play in the streets.
Many of the ball games featured are most often played with a pink rubber ball called a Spaldeen. Anybody who grew up playing these games can be transported back to their childhood just by smelling a Spaldeen. In the documentary, in fact, Whoopi Goldberg is seen discussing her childhood, and handling a Spaldeen. At some point, she puts the ball to her nose and smells it you can tell by the look on her face that she is transported by her memories of playing games with a Spaldeen as a child.
