Specially designed for children under the age of 11, this clever piece of equipment exercises the brain as well as the arms and shoulders. Much like rubbing their tummy and patting their heads, children can use the spinners in a variety of directions, moving both hands in the same or opposite directions. Easy-to-use, children can set their own speed and motion, working shoulder and arm muscles whilst building the communication between the two sides of the brain, which is crucial for language development.
