Its system of polymer links expand and contract almost effortlessly, changing in volume 30 times. A sturdy toy, an object of art, a tool for teaching mathematics and science - the Hoberman Sphere's universal appeal and versatility have led its owners to discover uses even its inventor never dreamed of. Children love to wear it on their heads, or climb inside. Grown-ups have proved themselves no less inventive: jugglers juggle with them. Drill teams march with them. Magicians make magic with them. Teachers teach geometry with them. Motivational speakers use them as metaphors for unity, teamwork and expanding potential. Ages 4 and up. Expands from 9.5\" to 30\".","brand":"John Hansen Company","offers":[{"title":"Default Title","offer_id":35646052401309,"sku":"14327","price":17.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0436\/3203\/3949\/products\/14327-kid.jpg?v=1597258114"},{"product_id":"free-fall-tube","title":"Free Fall Tube","description":"A very ecconomical apparatus to demonstrate that light and heavy objects fall at the same rate \/ accelaration in a vacuum.

The flexible handle and location of the suspension point above the center of the tray ensure that the forces on the liquid are always directed toward the supporting tray, even when the tray is in motion. Sideways forces usually responsible for spills are not transmitted to the tray by the flexible handle. Radial forces generated during swinging motion only force the liquid into the container more firmly. An inexpensive demonstration to intrigue students and challenge their analytical powers!

A steel ball rests on a thin metal card on top of a pillar, and a spring-loaded catch is mounted next to the pillar. When the catch is released, a piston strikes the edge of the metal card sharply. The card flies out from under the ball, which remains in place on top of the pillar due to its large inertial mass. The card is tethered to the aluminum base for easy recovery after the experiment.\u003cbr\u003eThis robustly constructed inertia demonstrator works reliably every time and is a great improvement on traditional versions of this classic experiment.
