The secret of Mona Lisa's smile is revealed in Manchester

An exhibition celebrating the inventions of Leonardo Da Vinci opened at Manchester's Museum of Science and Industry over the weekend.

It includes interactive models, a chance to copy his work and try your hand at inventing a few things, as well as the secret of Mona Lisa's smile - a series of x-ray photographs revealing the original colour of the 500-year-old painting and the skills used by the artist to depict Mona Lisa's famous smile.

The exhibition opened on Saturday and will run until the 13th June 2010. Tickets cost £7.50 for adults, £5 for concessions or £20 for a family ticket.
