Part of this is down to its interactive approach, which will appeal most of all to kids.
Highlights include the Dark Ride, a scientific journey through Malaysia, an interactive Formula One motor racing car; a 3D cinema; and a cartoon village.
On the flip side, Petrosains is also a shameless propaganda vehicle for the petroleum industry -- the centre is owned by Petronas, Malaysia's largest oil and gas company.
You would imagine that this would bring the price down, but it's certainly not cheap, particularly for non-Malaysians.
