Haven’t seen this mentioned yet so:

The honey may not expire, but the container you store it in could. I’d be very concerned about plastic disintegrating and/or leeching into the honey. Glass would be better for that, but it’s also really heavy compared to plastic, so you’d need more, smaller containers instead of one giant tub.

“Just chewing on plastic, what’s going on with you?”

Yes, most chewing gum is literally made of plastic, because of course it is.

Those devices absolutely need regular cleaning, because they will get moldy and will spew dirty air everywhere.
