Material:\u00a0<\/span>\u00a0<\/span><\/h2>\n
    \n
  • Glass bottle\u00a0<\/span>\u00a0<\/span><\/li>\n
  • clapper, e.g. teaspoon\u00a0<\/span>\u00a0<\/span>\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

    Instructions:\u00a0<\/span>\u00a0<\/span><\/h2>\n

    Whistle:<\/strong>\u00a0\u00a0<\/span>\u00a0<\/span><\/p>\n

    Blow into the neck of the bottle until a sound is produced.\u00a0\u00a0<\/span>\u00a0<\/span><\/p>\n

    Fill different amounts of water into the bottle and listen to how the sound changes.\u00a0\u00a0<\/span>\u00a0<\/span><\/p>\n

    Bell:<\/strong>\u00a0\u00a0<\/span>\u00a0<\/span><\/p>\n

    Tap the bottle with the clapper to make a sound.\u00a0\u00a0<\/span>\u00a0<\/span><\/p>\n

    Again, fill more water into the bottle and pay attention to the change in the sound.\u00a0<\/span>\u00a0<\/span><\/p>\n

    Observation:\u00a0<\/span>\u00a0<\/span>\u00a0<\/span><\/h2>\n

    Whistle:\u00a0\u00a0<\/strong>\u00a0<\/span><\/p>\n

    Blowing into the bottle produces a sound like a whistle.\u00a0\u00a0<\/span>\u00a0<\/span><\/p>\n

    The higher the water level, the higher the tone.\u00a0\u00a0\u00a0\u00a0<\/span>\u00a0<\/span><\/p>\n

    Bell:\u00a0\u00a0\u00a0<\/strong><\/p>\n

    Tapping the bottle with a spoon also produces a tone. This time, however, the pitch decreases as the water level increases.\u00a0<\/span>\u00a0<\/span><\/p>\n","protected":false},"featured_media":1272,"template":"","meta":[],"product_brand":[],"product_cat":[939,948,858],"product_tag":[],"class_list":{"0":"post-1269","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-13-oscillations-waves","7":"product_cat-16-acoustics","8":"product_cat-a-mechanics","9":"","10":"woocommerce-text-align-left","11":"woocommerce-image-align-center","13":"first","14":"instock","15":"shipping-taxable","16":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product\/1269","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/media\/1272"}],"wp:attachment":[{"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/media?parent=1269"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product_brand?post=1269"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product_cat?post=1269"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product_tag?post=1269"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
