The planetorium is one place you should visit when you come to Trivandrum. It was a novel experience for me when I found myself reclining in one of those chairs 2 weeks ago. I have been to one earlier. But that was ages ago. This might be very interesting for kids. As for me I enjoyed sitting under the dome, looking at the stars. And slowly it all started to whirl....And before I forget, this is their number: 2306024.
I found the experience soothing, relaxing and different. There is a science museum, but it was not my cup of tea. But I did see a super computer there called Param. Really huge and ancient looking in design. They also have a small park where they have kept some solar water heaters. Model rockets grace the entrance of the building.
The govt could probably use the rooms they have here for science exhibitions or conferences or something. These are kinda huge empty buildings located in the heart of the city.
The shows are run when 40 people have registered. Not less. They also have a 3D show, I saved that for next time.
