The kit includes a digital clock, wires, copper and zinc strips, and instructions, requiring two potatoes (not included) to operate. Kids can also experiment with other liquids like soft drinks and juice, or different fruits, to activate the clock and explore which materials conduct power. Featuring a large clock display that's easy to read, this hands-on project teaches how to power a clock without batteries while revealing the science behind electrical circuits and conductive power.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eUses two ordinary potatoes to create an oxidation\/reduction chemical reaction that powers a digital clock\u003c\/li\u003e \u003cli\u003eIncludes digital clock, wires, copper and zinc strips, and instructions; potatoes not supplied\u003c\/li\u003e \u003cli\u003eExperiment with soft drinks, juice, and other fruits to test which materials activate the clock\u003c\/li\u003e \u003cli\u003eLarge display makes it easy to read the time while learning about electrical circuits and conductive power\u003c\/li\u003e \u003cli\u003eSuitable for ages 8 and above\u003c\/li\u003e \u003c\/ul\u003e","brand":"Flat River Group","offers":[{"title":"Default Title","offer_id":50272198918360,"sku":"G4893156032751","price":18.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0675\/0476\/7192\/files\/ulurktg7j5ryx2situ0c.jpg?v=1742357652","url":"https:\/\/toysrux.com\/products\/green-science-potato-clock","provider":"Toys\"R\"Us","version":"1.0","type":"link"}
