There was a time when science city used to be a craze among all age groups. Happened to visit the place recently after may be a gap of 10 long years. The place is in urgent need of renovation, upgradation and maintenance. The fun experiments with whom one can learn with enjoying the phenomenon. 90% of them aren't working. The time machine is enjoyable yet the video quality is so poor that one doesn't get the exciting feel. A new HD video is needed for simulation. Same is the case for 3D shows. Please pay attention otherwise once an amusing place has already started decaying. And last but not the least, the food stalls available are sub par and charge high tariffs, need professional food joints inside, but given the sorry state of the place, I presume no vendor of repute will be enthusiastic about it.
