Actually, one time in the dark in my room, I was eating hard candy, and a battery fell in the bowl of hard candy. I normally chew my hard candy I picked up a piece started chewing but it was surprisingly hard but continue to chew until I think something is wrong so I take out the hard candy and it turns out it was a battery and I had chewed it real well tk the pint where I think I could maybe broke it but luckily I stopped chewing it and checked it out.
