The American Museum of Natural History is one of my favourite places - it was great to visit again, crowds & all. When we lived in New York, I was a volunteer at the museum - I recommend the program to anyone living in the city (you don't have to be a scientist, in my group there was everything from lawyers to bodega owners).
@cyrilpedia I enjoy the sealed sphere with the aquatic ecosystem that has been cut off from the outside world for 50 years or so and still functions and supports multicellular life
