Located in Midtown Manhattan, New York City, the museum is aimed at children aged 8 to 13. The designers and curators have given the place a playground feel. The 40 exhibits include a "wall of fire" made up of laser lights that teaches kids about geometry and a square-wheeled tricycle that still manages to produce a smooth ride thanks to a wavy track.
