When the ball or ring is heated, the ball will not pass through the ring. When cooled, however, the ball passes through the ring freely.\u003cbr\u003e\u003cbr\u003eThe ball and ring are mounted on an insulated handle. Instructions included. Ball and Ring Apparatus designed for demonstrating the principles of thermal expansion in educational settings. Hands-on demonstration tool that visually illustrates how materials expand when heated and contract when cooled.\u003cbr\u003e\u003cbr\u003eIdeal for physics lessons, helping students understand thermal properties and material behavior under temperature changes. Simple yet effective design makes complex scientific concepts accessible and engaging for students of all ages.","brand":"GSC International","offers":[{"title":"Default Title","offer_id":49956250026261,"sku":"GSC4-19801-CS","price":1420.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/4-19801-CSRINGBALL-Photoroom_1.jpg?v=1780892372","url":"https:\/\/unitedsupplycorp.com\/products\/ball-and-ring-apparatus-educational-demonstration-of-thermal-expansion-case-of-100","provider":"United Supply Corp.","version":"1.0","type":"link"}
