Here at Mosaic we like to reduce our waste as much as possible. It’s just plain bad for the planet. So we found an ice pack that disappears naturally, leaving virtually zero trace. Be careful -- dry ice is extremely cold. Make sure to wear gloves or use a pot holder when handling it. You can toss it in your backyard (if you have one!), or leave it a well-ventilated area at room temperature and it will evaporate overnight.
