Nagoya City Science Museum

The planetarium dome is 35 meters across and was recognized by Guinness World Records in 2011 as the world's largest. Exhibits cover physics, technology, life and the environment, and many of them can be touched and tried. Highlights include a 9-meter tornado lab, a discharge lab with large Tesla coils, and a cold lab that reaches minus 30 degrees Celsius. Outside stand a test airframe from the H-IIB rocket development program and a structural test model of the Kibo module of the International Space Station. Many exhibits are aimed at children, and the Nagoya City Art Museum is next door.
