Coffee balls are going to be the new craze for coffee drinkers. The idea is to get rid of the little cups that everyone’s been using for the last 10 years. So, these things are compact balls of coffee that you drop into the top of the personal coffee machine. They do come in a clear casing, but it biodegrades within 4 weeks. The coffee machine looks like a humidifier with a water tank on the back. There’s a ball holder on top that holds about 12 balls and rotates to place the next one in for you. They also say that the coffee balls will be much cheaper than what comes in the little cups.
