I just couldn't wait until morning. Around midnight I was rinsing this one out in a bowl out on the deck, in the dark.
I did not examine the cream of wheat closely but it looks like the bugs (and their eggs?) took up the dye particles and redeposited them according to their size - you can see the ghosts in blue here. the brownish lines came from the radiator where I draped this to dry for just a few minutes. Live and learn with that one.
