This activity provides visual stimulation while individuals watch the rings spiral downward. They are encouraged to reach above their eye level to develop better postural control while also using both hands together to attach the rings. The coil is half of a hose that I came across, its a really nice tube that stays coiled up up after it is pulled upward. Pulling it provides wonderful proprioceptive stimulation to muscles and joins and is just fun to feel the springiness as it moves up and down. I attached a bag of sand to the bottom of one of these to help keep the bottom of it on the floor. Then I realized that if I attached a sock to the bottom of another one, the individual could stand on it and work on balancing while reaching to take more rings. It was quite the challenge for some of them to sequence these steps and it certainly worked on body awareness and motor planning !!
