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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
