A wooden balancing toy that children love to experiment with. Hook the monkeys into the branches on either side of the tree at varying points along branch to alter the effective weight and tip the balance. One monkey placed near the tree on one side has a different effect to one monkey placed further away from the tree on the other side. It's like a little physics lesson for the whole family and it's great fun too. Helps develop early mathematical skills and problem solving... looks pretty snazzy too.
