The only time I made a toxic soup was by accident, while madly cleaning in the middle of the night (nesting )
I had put a but of bleach into all the mugs, sitting in the sink, to get rid of tea rings in them.
While they were soaking , I used other cleaners to scrub the floor.
I poured my bucket of cleaning water down the sink, somehow forgetting the cups were in there. Also likely thinking I was about to empty them in a minute and wash them.
Then went and got new water and back down scrubbing on the floor.
While I was down there, gasses were mixing and brewing and rising, and somehow I don't notice right away
I started getting a hacking cough, and I didn't feel good.
I got up from the floor and made it to the bedroom, and DH woke as I came in.
Right away, he starts coughing and saying ," omg, what is smell"
He jumped up and saw right away, pulled the plug and drained everything and made the call to poison control.
I was scared I'd have hurt the baby, first pregnancy, freaking out.
Basically we had to leave the apartment, for ages, and leave all the windows and doors open to air it out, but no longer term issues.
Ok, so it wasn't cooking, but it was in the kitchen, and t was a toxic mix.
Who knew how easy it is to make chlorine gas?
