{"product_id":"united-scientific®-tuning-fork-set-of-4","title":"United Scientific® Tuning Fork Set of 4","description":"Tuning forks are excellent tools for students to investigate resonance and pitch. A simple strike of a tuning fork onto a rubber surface demonstrates how its length affects the pitch that it creates. Tuning forks are useful in providing sound for resonance tubes or for exploring the Doppler effect. \nTuning Fork Set of 4 contains one each of 256 Hz, 320 Hz, 384 Hz, and 512 Hz forks.\nPlease note: never strike a tuning fork on a hard surface or against another tuning fork.","brand":"United Scientific Supplies","offers":[{"title":"Default Title","offer_id":49962283729173,"sku":"USSTFSET4","price":21.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/TFSET4_20Tuning_20fork_20set_20of_204.jpg?v=1781070051","url":"https:\/\/unitedsupplycorp.com\/products\/united-scientific%c2%ae-tuning-fork-set-of-4","provider":"United Supply Corp.","version":"1.0","type":"link"}
