Standard Skittles candies come in red, yellow, orange, violet, and green. Do you have a favorite? To the best of my knowledge, they all taste the same. But if you're picky about the color, then this automatic Skittles color sorter is for you.
Alice Kassar, Jesse Checkla, Mikhail Rudinskiy, who are students at Cornell University, made it a class project. It exposes the Skittles to light, then determines the color based on the RGV values reflected back. A sorting arm adjusts to move each Skittle into the correct silo, which feeds it into a bag. Pull the bag across a hot wire to seal it and then you've got a bag of monochrome Skittles.
