Located within the imposing Petronas Twin Towers building, Petrosains is a modern museum housing many exciting exhibits. Covering a total area of 100,000 square feet, this interactive science discovery centre traces the development of petroleum science and technology. Among the interesting exhibits are hi-tech presentations of a singing dinosaur and a smoking volcano. The discovery journey through forest, ocean and sky, and the simulation helicopter flight in a tropical storm is just as thrilling and engaging. There are also live science demonstrations and a child play centre. Admission: RM12 (adults), RM4 (children).
