Today I was teaching a sort of intro to survivalism class to my 5th graders. The activity required them to pick ten essential supplies out of a pack of cards with different items written on them. One kid picked a card that said “water and iodine tablets”, which was correct, but a parent chaperone told her to put it back.
“Iodine is only for nuclear stuff,” he said. “You don’t need it unless you’re making bombs. This is a trick question, I don’t even know why they’d write that on here.”
Iodine is, of course, used to disinfect water from natural sources so that it’s safer to drink.
My apologies that I don’t have the image credits (though I do know that several are from the 5e DMG). It’s been a while since I started putting these together. If there are any issues, or you know the image source, please let me know!
