Bring a bit of that summer time, ball game concession stand, block party, sticky hot heat nostalgia into your life now with this Cotton-Candy machine tutorial from PopularScience.
A DIY cotton-candy machine consists of a small metal container, repurposed lighter parts to provide heat, and a switch-controlled motor to set everything spinning. Slowly pour granulated sugar into the container, and flames from the lighters will melt it. As the motor spins, the liquid sugar will fly out through little holes in the container’s sides, forming thin strands. A paper cylinder placed around the machine will capture them. Once they’ve built up, simply swirl a chopstick around the perimeter to gather the candy and taste your sweet success.

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.
