From ‘Dancing Fluorescent Droplets’ to ‘Metal Displacement’ Watch Beautiful Chemical Reactions Up Close!
It’s pretty astounding to consider what occurs at such small scales that a hi-definition microscope and special macro lenses are required to see what is happening! For example this GIF is what happens when cobalt chloride and sodium silicate encounter each other.
You don’t have to know your Zn(NO3)2 from your CuSO4 to appreciate these absolutely beautiful videos of chemical reactions created for a site called Beautiful Chemistry.
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.
