A few weeks ago, I was picking on my teenage daughter by calling her generation the Tide Pod generation. She doesn't like this very much when I say it. She then went on to admit that one of her friends put a Tide Pod in his mouth. It evidently started to dissolve almost immediately and he spit it out. Yes, he tried a Tide Pod. By the way, his ACT score was 36.
I will say I think the hot water thought may have been off, but cold water loads probably do create issues.
