Science City is a must visit spot for any tourist who has some spare time in Kolkata. For a nominal fee, one can enjoy the Ropeway ride, a 3D show that is really exciting and a space theatre documentary movie. There are more to it-Mirror mazes, butterfly cages, cool high school science experiments on display and a very nice Mono-cycle which is basically like a cycle at some altitude which is paddled and moved on a single metal sheath.
The food inside is not very good, but ice cream and tea are welcome choices. There is a Naval centre that displays models of old age to modern hi tech ships and submarines. Science City has something for everyone.
