I was about to use one of those chemical cold-packs for a sore foot, and, instead of activation, I get covered with a fine mist of ammonium nitrate and water.
Bomb-sniffing dogs in UTAH just woke up. Argh.
Good thing it didn’t have diesel fuel in it.
Sometimes, I wish they came with a gallon of kerosene and a book of matches.
But did it help the foot? We might have a new treatment plan! I see web pages…books…infomercials…$$$$
