I visited there know-how town in Kolkata two times in a year with my family and I just wanna say that it became a completely awful and hectic experience. First of all the technological know-how city is well-known for their innovations and new experiments but here they still have the ones 10 yr antique experiments and model on display which aren’t even running properly, they need to have updated all of it with the time . Secondly the provider turned into very awful we didnt even wenmre explained it properly by using the guide and he became in so rush that he skipped some of the experiments which have been running and had been nevertheless good.
