Cool website of the day: Der Lauf der Dinge
Hip and cool summer art on the High Line: A looped showing of Peter Fischli and David Weiss's 1987 30-minute film, "The Way Things Go" (Der Lauf der Dinge).
The artists made an industrial monster Rube Goldberg chain. I can't think of a better demonstration for introducing young kids to why physics and, to a lesser extent, chemistry matter and how the two fields can interact in interesting ways. A technical explanation for each step would enhance the viewing experience.
