Recently I have visited a Birla science center which is near Birla Mandir. I have seen it enjoyable. There were many models of the greatest invention of science.
Some of the students who are working as volunteers are answering the queries of the visitors.
It was really informative and educative. If you have time, I strongly recommend you to visit it once. The place is also so pleasant and beautiful architected the entire Birla science center, Birla Temple and all sorroundings.
