Gravinky Air Ink

Some extremely smart people have figured out how to make ink from air pollution. That’s not a gimmick either, they really do collect pollution and make deep black ink. It’s not really a surprise this comes from an MIT lab. With their devices, they can collect enough soot to fill a pen that you can get for a pledge of $35. Just think how much pollution we could negate if all black ink were eventually made this way. Heck, even grey tones could be made this way. I bet those smarties could even figure out a way to do colors. I applaud the effort and think their campaign is worth supporting.
