Did you know that the giant sequoia is the tallest tree on Earth or that clouds are formed by billions of tiny ice crystals? BrainBox Nature is packed full of interesting facts about nature in 70 beautifully-illustrated cards. The object of the game is to study a card for 10 seconds and then answer a question based on the roll of a die. If the question is answered correctly, the card is kept, and the person with the most number of cards after 5 or 10 minutes is the winner. Made from a minimum of 70% recycled material and designed in the UK, the BrainBox range is fabulous fun.
