Pacific Science Center is an independent, non-profit science center in Seattle with a mission to ignite curiosity and fuel a passion for discovery, experimentation, and critical thinking.
The center's original buildings were the United States Science Pavilion designed by Minoru Yamasaki for the 1962 World's Fair in Seattle. During the 1960s, many of the center's exhibits were carried over from the original World's Fair exhibition, though only a few of these original exhibits remain. Currently, exhibits remaining from the World's Fair are the Lens and Mirror Machine and a suspended model of the Earth's moon.

In the mid-1970s, the lower-level math area was dominated by the IBM Mathematica exhibit where demonstrators in orange jackets (known as "OJ"s) made soap bubbles and showed audiences how the stylish new Chevrolet Chevette was paving the way for the quick adoption of the Metric system. Upstairs, a giant apparatus known as the probability machine would ring an alarm before emptying out a bin of balls. This machine was originally designed as an exhibit for the IBM Pavilion at the 1964-65 New York World's Fair.

Today Pacific Science Center is composed of eight buildings, including two IMAX theaters (one of only a few places in the world with more than one IMAX theater), one of the world's largest Laser Dome theaters, a tropical butterfly house, a planetarium, and hundreds of hands-on science exhibits. In addition to a number of permanent exhibits the Center also hosts a variety of traveling and temporary exhibits.
