The Science Of Beer And Cavitation #SaturdayMorningCartoons
You know when you tap the head of an open beer bottle and beer bubbles everywhere? Maki Naro explains the science behind it! via popsci
What neither the perpetrator nor the mark are aware is that they have just demonstrated a phenomenon known as cavitation. When liquid, such as our beer, undergoes a rapid change in pressure, it spurs the formation of vapor cavities (hence the name) in low pressure areas. At the 66th Annual Meeting of the American Physical Society Division of Fluid Dynamics, researchers from the Carlos III University of Madrid, Spain and Universite Pierre et Marie Curie, Institut Jean le Rond d’Alembert, France demonstrated how this series of expansion-compression waves can cause the rapid degasification of beer.
Even cooler is this video of cavitation being done in a beer bottle that only contains water!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
