Looking for some steamy industrial fun this weekend? We choo-choo-choose this replica of George Stephenson's Rocket, which is currently doing the rounds (literally) in Kensington Gardens. The 'Mocket', as we shall dub it, takes passengers on a short ride around part of the gardens for just £5 (adult) or £2.50 (kids). Unless you're Prince Philip, this is perhaps your only opportunity to ride something that's featured on a five pound note. When you're done, go visit the original Rocket (from 1829) at the Science Museum, currently celebrating its centenary. The ride will be in place until 18 April. Image by sc63 and used with permission.
