Sea Life London Aquarium is hosting a special After Dark event to celebrate the brand new Lego City Deep Sea collection making a special appearance at the aquarium. Enjoy a reception drink on arrival and prepare yourself for passing over the Shark Walk – a glass walkway above the magnificent Pacific Reef display. Be warned, sharks will be swimming just inches from your feet. Visitors will be challenged to build their own Lego masterpiece and help a Lego master builder create a giant 70cm shark made entirely out of Lego bricks. Over 18s only. No admission after 9pm. The penguin exhibit will be closed during the event.
