The Kew Bridge Steam Museum is renamed the London Museum of Water and Steam, and reopens on March 22 after a £2.3 million refurbishement. It tells the story of how the Victorians cleaned up London's water supply and paved the way for the modern city. There will be two new laboratory areas where kids can examine clean and dirty water, and an outdoor Splashzone where they can make jets of water travel to heights of 5 metres using a network of pumps and pulleys. Take a change of clothes!
