Okay, so maybe it was really a vacuuming that the American Museum of Natural History Museum's Blue Whale received. But now you know that's how the 90-foot fiberglass model, which hangs in the Hall of Ocean Life, is cleaned: An industrial sized vacuum, a scaffold, and the attention of Rodolfo Valencia. Valencia gave the whale its last cleaning two years ago—a lot of dust has piled up since then! The AMNH told the Post, "It's his baby. He's very gentle with it. He's got this all mapped out. He probably knows every inch of that whale."
