{"product_id":"bell-in-bell-jar-1","title":"BELL IN BELL JAR","description":"\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003eWithout air or objects, sound waves cannot travel and thus cannot be heard. This principle is effectively demonstrated by the bell jar, which contains a battery-operated buzzer. When the buzzer is placed beneath the jar and a vacuum is produced within, learners will notice a complete lack of sound. Once the air has been reintroduced to the jar, the buzzer will sound again. The activity requires a vacuum pump and a plate, which are not supplied.\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable border=\"0\" cellpadding=\"0\" cellspacing=\"0\" width=\"296\" style=\"border-collapse: collapse; width: 321px;\" height=\"38\"\u003e\n\u003ccolgroup\u003e\n\u003ccol width=\"97\" style=\"width: 110.5px;\"\u003e \u003ccol width=\"199\" style=\"width: 209.5px;\"\u003e \u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr height=\"20\" style=\"height: 15.0pt;\"\u003e\n\u003ctd height=\"20\" class=\"xl65\" width=\"97\" style=\"height: 15.0pt; width: 73pt;\"\u003e\u003cstrong\u003eCategory No.\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"xl65\" width=\"199\" style=\"width: 149pt;\"\u003e\n\u003c!-- x-tinymce\/html --\u003e\u003cstrong\u003eDescription\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"20\" style=\"height: 15.0pt;\"\u003e\n\u003ctd height=\"20\" class=\"xl66\" style=\"height: 15.0pt;\"\u003e\n\u003c!-- x-tinymce\/html --\u003e101766\u003c\/td\u003e\n\u003ctd\u003e\n\u003c!-- x-tinymce\/html --\u003e\u003cspan data-sheets-root=\"1\"\u003eBell in Bell Jar\u003c\/span\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003eH46\u003c\/span\u003e\u003c\/p\u003e","brand":"japson.com","offers":[{"title":"Default Title","offer_id":45282351087725,"sku":"101766","price":0.0,"currency_code":"INR","in_stock":true}],"url":"https:\/\/japson.com\/nl\/products\/bell-in-bell-jar-1","provider":"japson.com","version":"1.0","type":"link"}
