welcome to the lab.
I was super curious to see if ketchup could work as an ink. So, I decided to be an ink scientist for a while. I picked up Gatorade (C), Ketchup (M), Mustard (Y), Espresso (K) to make CYMK ink. And I tried to see the difference: the real ink vs Ketchup ink. I, one-day ink artist, was truly happy. And I tried to sell it on eBay. No one caught it so far.
