You could be eagerly anticipating your morning Keurig, and then POW! coffee grinds everywhere. Not a very pleasant way to start your day.
I had heard of this happening to a handful of Twitter people then recently my father-in-law had a K-Cup explode on him, too. He called Keurig to find out why it happened, and they said that if too much air is in a K-Cup (you’ll notice the top is very rounded), it is at risk of rupturing when the nail clamps down on it.
To protect from this messy, jarring event, Keurig advised him to poke a tiny hole with a needle in any of these risky-looking K-Cups to let out a little of the extra air.
I think I’m going to take my chances for now. I like to live dangerously!
