Taste the Rainbow one Color at a Time with a Color-Sensitive Skittle Sorter


(Video Link)

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.

Skittles do taste different. The five original flavors were all sweet fruit flavors. Then they decided to change green from lime to green apple. So now you've got 4 sweet flavors and one bad sour apple version that leaves a chemical aftertaste.

The rainbow is ruined.
