The attraction has launched new exhibits including seven real fossilised dinosaur eggs, a vintage lamp carved from ostrich eggs and a two headed lamb - just one of more than 700 bizarre exhibits at the central London attraction.
This Sunday (April 8) visitors can also try their luck at 'Russian Roul-egg' for the chance to gain free entry to the attraction. The challenge will see visitors asked to pick an egg at random from a box of six and smash it on their head. While five will be hard-boiled, one of the half-dozen will be raw.
Anyone lucky enough to 'survive' by finding a cooked egg will win a free ticket to Ripley's Believe It Or Not! London - home to thousands of weird exhibits from around the world including a life sized knitted Ferrari and real Ecuadorian shrunken heads.
The Roul-egg challenge takes place between 11:00 and 14:00 with one free entry per family or group.
Ripley's Believe It or Not! is open seven days a week, 365 days a year from 10:00 until 24:00.
Ultimate Explorer tickets cost 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.
