Petrosains Kuala Lumpur is a 7,000sqm interactive science discovery centre located on the fourth floor of the Petronas Twin Towers. Good for a few hours of fun-filled activity, the complex is largely dedicated to the field of petroleum science and presents science and technology in a fun and entertaining way. Arranged in an easy-to-navigate ‘museum-style’ concept with a collection of everything from space age exhibits to fossils, it is also a great place to learn more about other scientific issues. Since its opening in 1999, this hands-on interactive science museum has been popular with locals as well as expatriate families. Petrosains Kuala Lumpur is divided into 11 main interactive showcases, which can be visited in any order.
