National Science Centre

 It's what to do on a hot day in Delhi.
We thought.
Mistakenly, we believed the science museum would be air-conditioned.  And I supposed it was, sort of, but not fully. 

Escape from the heat or not, there are still a few things to do there...

...see an ancient surgery taking place, for one.

Look at cannons.
Even Akbar makes it to the science museum.  These are his portable cannons, the first of their kind, an innovation in weaponry.

The most fun are the mirrors--mazes, distortions, and fun angles.

Keep your expectations low--and I mean low--and it's a good outing.
