Dalian, China-based videographer Wenting Zhu spent seven months creating The Arctic, a time-lapse video that explores the vastly different crystallization processes of salts. Crystals formed from salts including potassium nitrate and sodium sulfate explode like fireworks or appear to freeze like ice when seen through an accelerated lens. The film was created for Beauty of Science (previously), an ongoing series that presents aesthetically intriguing videos about science with a focus on chemical reactions.
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.
