How heavy are Coffee Joulies?

Last Updated: Jan 31, 2013 06:14PM EST
Each Joulie is a thin hollow shell filled with a lightweight phase change material so they are only 50% heavier than the same size ice cube. This means they sink and are out of the way while remaining easy to manage. The first thing you notice is that they are lighter than they look.

More specifically they weigh about 31 grams or about 1 oz each.
