{"product_id":"metal-tippe-flip-over-top","title":"Metal Tippe \"Flip Over\" Top","description":"\u003cp\u003e\u003cspan\u003eThis spinning top has a surprising behavior. When spun, it will introvert itself to spin upside down until it loses momentum. This interesting gyroscopic effect is generally credited to surface friction. This small friction causes a torque which gradually rotates the sphere on a second axis and forces it up onto the stem. Note the direction of rotation before and after it flips.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThis precision tippe top was machined from aluminum to achieve the best effect. It takes a good spin to successfully flip, so have patience if it doesn't happen right away.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e(Pictured: Bohr and Pauli investigating a tippe top).\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eDiameter: 29mm (1.14\") \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eHieght: 36mm (1.41\")\u003c\/span\u003e\u003c\/p\u003e","brand":"Stemcell Science Shop","offers":[{"title":"Silver","offer_id":53173801648239,"sku":"TI-0071","price":8.3,"currency_code":"USD","in_stock":false},{"title":"Gold","offer_id":53173801681007,"sku":"TI-0072","price":8.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0715\/2074\/7631\/files\/metal-tippe-flip-over-top-stemcell-science-shop-ti-0071-739590.jpg?v=1780156881","url":"https:\/\/secretstashspot.com\/products\/metal-tippe-flip-over-top","provider":"SecretStashSpot ","version":"1.0","type":"link"}
