Pop Toobs strengthen muscles involved in two-handed activities and provide auditory, visual, and tactile feedback. Simple accordion tubes pull apart–up to 29″–and scrunch back to 8 1/2″, bend, snap together, and pull apart. Bend one into a circle, snap the ends together and wear as a crown. Or toss and see how far it flies. Connect one to another and then another. How many can you connect? How long is the chain when all the toobs are pressed together? When they’re pulled out as far as each will go? Play and learn while developing muscle strength. Available as a 6-pack or 24-count box.
