How many times have you burnt your tongue when you took a sip of coffee that was still too hot to consume? In my case, I’d say it’s one too many. I hate the sandpaper-like feeling of a burnt tongue that makes eating and drinking uncomfortable for a couple of days. Of course, you can avoid this simply by checking the beverage’s temperature before taking a sip. Or you can just get one of these temperature-sensing mugs from Brando.
