It's more than 8ft long, took more than 3,500 hours to construct and features 1,600 intricately carved portholes – but can you guess how many matchsticks were used to make the Titantic model, on display at Ripley's Believe It Or Not! London?

The London-based attraction is inviting followers on twitter (@RipleysLondon) to enter a prize draw for a chance of winning free admission to Ripley's and tickets to a screening of Titanic 3D by guessing how many matchsticks were used to make the scale model of the famous luxury liner.

Ultimate Explorer tickets start from £26.95 per adult and £21.95 per child, including entry to the Mirror Maze and the new LaseRace. Ultimate Explorer family tickets are available for £87.95, based on two adults and two children.
