Went on a Monday following Hurricane/Tropical Storm Irene. Museum was virtually empty. Went with 3 children - two teen boys and an eleven year old girl. Almost every exhibit was a hands-on type which really made the difference. The staff was excellent and patient. For example, they were willing to accommodate my daughters repeated requests to use the shadow room where a strobe light leaves a shadow impression on a glow in the dark wall. This is not a place where you will spend all day - two hours is sufficient. It is very clean and fun. The only food available that day for those interested was a few vending machines. Other than my son's souvenir yo-yo breaking almost immediately it was a good time.
