The Beauty of Science (BOS) has a stunning new video online dedicated to electrodeposition. This is a chemical reaction in which positively charged metallic ions, called cations, suspended in a liquid solution are attracted to a negatively charged electrode, called a cathode. In the process, the metal molecules form gorgeous structures as they pile up and organize themselves.
The BOS team led by Doctor Yan Liang used a microscope and exquisite photography to film copper tin, zinc, lead, and silver. Thanks to their different chemical properties, each of these metals created distinct shapes. The constructions resemble other fractal structures like crystals, coral, algae, leaves, and trees.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
