My favorite place in New York’s American Museum of Natural History is the Milstein Hall of Ocean Life, where a 94 foot long blue whale appears to be swimming through space.  The whale is a 21,000-pound fiberglass model of a female blue whale found in 1925 off the southern tip of South America.  The whale was installed in 1969. Every year the whale is cleaned using a special vacuum cleaner.  This year the cleaning process was streamed live over the internet.  In case you missed it, here is a two minute summary of the two to three day cleaning job.
