welcome to the lab.
In 2016, I was super curious to see if ketchup could work as an ink. So, I decided to be an ink scientist for a day. I picked up Gatorade (C), Ketchup (M), Mustard (Y), Espresso (K) to make a CYMK ink set. And I tried to see the difference: the real ink vs Ketchup ink. It worked! So, I put up the stuff on eBay. No one caught it so far.
