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

Balancing bird (made of hard plastic), available as a ready-made product.\u00a0<\/span>\u00a0<\/span><\/p>\n

Instructions:\u00a0<\/span>\u00a0<\/span><\/h2>\n
    \n
  • Place the bird on a finger with the tip of its beak.\u00a0<\/span>\u00a0<\/span><\/li>\n
  • Let the bird sway on the finger.\u00a0<\/span>\u00a0<\/span><\/li>\n
  • Make the bird turn slowly.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

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

    Neither while swaying nor while spinning does the bird fall off the finger, its position is stable.\u00a0<\/span>\u00a0<\/span><\/p>\n

    Explanation:<\/h2>\n
      \n
    • There are weights hidden in the downward curved wing tips, so the bird’s center of gravity is well below the tip of its beak.\u00a0\u00a0<\/span>\u00a0<\/span><\/li>\n
    • The point of contact on the finger is therefore above the center of gravity. Thus, a stable equilibrium is maintained.\u00a0<\/span>\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n","protected":false},"featured_media":1242,"template":"","meta":[],"product_brand":[],"product_cat":[903,904,858,880],"product_tag":[],"class_list":{"0":"post-1240","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-1-mass-weight-density-center-of-gravity","7":"product_cat-2-force-equilibrium-of-forces","8":"product_cat-a-mechanics","9":"product_cat-g-magic-tricks-en","10":"","11":"woocommerce-text-align-left","12":"woocommerce-image-align-center","14":"first","15":"instock","16":"shipping-taxable","17":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product\/1240","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\/1242"}],"wp:attachment":[{"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/media?parent=1240"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product_brand?post=1240"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product_cat?post=1240"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product_tag?post=1240"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
