The kitchen is a fantastic place to witness the everyday beauty of fluid dynamics. Daria Khoroshavina and Olga Kolesnikova capture these delectable cooking-related GIFs on their Buttery Planet Tumblr. From pouring cream to drizzling syrup, there are countless examples of fluids in daily life. Check out their site for more awesome images and be sure to keep your eyes open for great examples of fluid behavior in your day-to-day life. (Image credits: Buttery Planet; via Colossal)
Ever notice the distinctive ring that forms in your kitchen sink when you turn the water on? This phenomenon is known as a hydraulic jump; it occurs when a fast moving fluid (the water just discharged from the faucet) runs into a slow moving fluid (the water that’s been sitting in the sink) and transfers some of its kinetic energy into potential energy by increasing its elevation. Researchers have recently shown that this everyday occurrence is actually a physical analog to a white hole, the cosmological inverse of a black hole. (In theory, a white hole cannot be entered, but light and matter can escape it.) Check out Wired’s article for an explanation of the clever experiment that showed the equivalence of the two. #
