The most popular exhibition items for children are a computer area, a real (but stationary) car in which visitors can attempt to drive in a driving simulation while avoiding accidents, speeding, and excessive fuel usage, and a small life-sized stationary aircraft with a video of a flight around Hong Kong playing inside the cockpit. Refreshments are provided at a small cafe.
About 500 exhibits are displayed in the permanent exhibition area. The most prominent exhibit is the 22-m high twin-tower Energy Machine which is the largest of its kind in the world. A total of 18 galleries cover a wide range of science and technology topics including light, sound, motion, electricity and magnetism, mathematics, life science, geography, meteorology, computer, transportation, communication, food science, energy/energy conservation and home technology. About 80% of the exhibits are participatory so that visitors may learn through direct involvement.
The museum staff also performs live demonstrations daily, many of which are designed for younger visitors.
