There ’s a family line - caption that hold that the best manner to see if a kid loves butter is to reserve a buttercup under their chin and see if it reflect atomic number 79 - chicken light on the kidskin ’s pelt . If it does , then clear they love butter . It seems strange that this legend sprang up , since the surer test would clear be yield a nestling a bathing tub of butter , a pitcher’s mound of mashed tater , and a spoonful , and seeing if they go to work . But you know kid ; they sleep with their unexampled technology .
Now , after one C of superstitious buttercup - chin juxtaposition , Cambridge scientists have unraveled the inscrutable mystery of buttercups . They now understand why the kingcup shines yellow light on anything near it , and this longstanding mystery has been ascribe to the cellular social organisation of the flower .
scientist have been trying to cypher out exactly why the butterflower tend to yellow up whatever is near it , more than any other flower . The flower ’s yellow coloration is a simple tendency of the petals to absorb blue - green light and shine yellow light . The buttercups divvy up this leaning with plenty of other flowers . What seems to make the difference is a unique top layer of the petals . Scientists have lie with for some prison term that the top layer of cells of the flower are stretched thinly , take in them shining as shabu , reflecting large amounts of light .
What ’s been recently discovered is a tiny stratum of air between the gloss and the petals . This is a microscopic rendering of the layer of bubbles coating the hulls of ship , or hands dipped briefly under the water . The stratum of air surrounded by glassy walls only slimly alter the color of the substance , but they throw off an immense amount of brightness level , making the object shine . The same force is happening with the butter-flower . The thin bed of air travel reflects so much brightness that it repeat the amount of lightness fall off the crowfoot . The result is a yellow glow that will act as a spotlight to pollinators and put all the other bloom to ignominy .
But not as much shame as those kids should feel .
