Prince William and Kate Middleton were all smiles when they visited the Eden Project, an educational charity that teaches people about the living world, in Cornwall, England. The royal couple looked completely amused as they explored the Rainforest Biome, the world's largest indoor rainforest, and came in contact with a few funny creatures. While William donned a blazer and khaki slacks, Kate added a pop of color with her jacket and printed blue trousers from Gap. Not only did the pair stop for a refreshing drink at the Baobab & Rum Bar, but the Duchess of Cambridge also shared a few laughs when she was greeted by a toy dinosaur. Later that day, the couple continued the fun by hopping on a boat to St Martins, waving at the crowd as they took off.
