High-Speed Camera Captures a Fluid Behaving Like a Solid
Photographers give us glimpses of the world that stand outside of time. Those moments can help us understand unique moments in physics. Using a camra that can capture images at 1,000 frames per second, researchers have recorded fluids behaving like solids. Here’s more from Engadget:
The team put a liquid mixture of corn starch and water into a narrow cell, and subjected it to pressurized air that resulted in Discontinuous Shear Thickening — that is, the fluid thickened and produced solid-style “fractures….” By itself, the study revealed what was possible with the material. You could turn the friction (and thus the fluid state) “on and off like a switch” just by varying the pressure.
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.
