Hope Everyone had an explosive 4th of July! Check out this video that explains the chemistry of fireworks, from Reactions.
From the sizzle of the fuse to the boom and burst of colors, this video brings you all of the exciting sights and sounds of Fourth of July fireworks, plus a little chemical knowhow. John A. Conkling, Ph.D., shows how the familiar rockets and other neat products that light up the night sky all represent chemistry in action.
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.
