Have to spruce up the rave cave with a recent bouquet? Feeding white flowers a water- and-highlighter ink cocktail creates psychedelic petals, because the Middle for Sustainable Nanotechnology demonstrates.
The experiment’s executed by pulling the ink effectively from a highlighter and squeezing it right into a vase — 10 drops for each ounce of water. Leaving flowers a bit of thirsty earlier than dropping their lower stems into the combination makes them drink it quicker. It takes a full day for the water-soluble fluorescent compound pyranine to take in to the petals, so plan your blacklight celebration accordingly.
