I wonder if (and I wish) battery producers could use the same "coating" as the Nintendo Switch cartridges. They taste disgusting and greatly reduce the risk of having a child swallowing them.
Why have you told me this, I now have an urge to go test this by licking a cartridge.
I don't have a cartridge. Please lick yours and report back.
They don't taste much worse than pills-for-adults – unless you dislike bitter things, I suppose. The goal is to stop very small children from eating them, not determined 6-year-olds.
I have regrets. It's really weird, super bitter.
It was less bitter than I expected. Closer to arugula than Fernet.
Don't worry, you're not alone - about 4 years ago it got reported on so everyone wanted to try it.
They already do on some. I bought a pack of 2032s (Duracell maybe?) a few weeks back that had the coating.
