{"product_id":"happy-sad-ball-set-hsb002","title":"Happy\/Sad Ball Set - HSB002","description":"Set of two black rubber balls, each 1-3\/8” in diameter, appear to be identical in terms of appearance and mass but are manufactured from different types of rubber. When dropped on a hard surface from an equal height, the happy ball bounces high and the sad ball barely bounces at all. The happy ball also rolls faster than the sad ball. Provides an interesting and memorable demonstration for studying elasticity, kinetic energy, and polymer composition.\u003cbr\u003e\u003cb\u003eAdditional Info:\u003c\/b\u003e Happy\/Sad Ball Set\u003cbr\u003e\u003cb\u003ePackage Size(L x W x H):\u003c\/b\u003e 3 X 2 X 1 (IN)\u003cbr\u003e\u003cb\u003eCategories:\u003c\/b\u003e Physics, Matter\u003cbr\u003e\u003cb\u003eHTS Code:\u003c\/b\u003e 4016.93.5010\u003cbr\u003e\u003cb\u003eUNSPSC:\u003c\/b\u003e 6.01046e+007\u003cbr\u003e\u003cb\u003eCountry Of Origin:\u003c\/b\u003e INDIA","brand":"United Scientific Supplies","offers":[{"title":"Default Title","offer_id":37110352871593,"sku":"HSB002","price":8.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0401\/5452\/9953\/products\/hsb002-happy-sad-balls.jpg?v=1709866486","url":"https:\/\/labproinc.myshopify.com\/products\/happy-sad-ball-set-hsb002","provider":"Lab Pro Inc","version":"1.0","type":"link"}
