As a child, did you ever shine a buttercup flower under your chin and witness a yellow glow to test whether you or your friends like butter?

The bright and glossy appearance of the buttercup petals is the result of the interplay between its different layers, The Telegraph reports. The yellow reflection responsible for the illumination is due primarily to the epidermal layer of the petal reflecting yellow light with an intensity similar to glass. The researchers also found a significant amount of UV light reflected from the flower which attracts many pollinators, including bees, which have eyes sensitive in the UV region. As far back as 1883, researchers had noted the unusual optical properties of the buttercup, but this is the first time scientists have
