The Spherical Ice Cube maker is great and all, but damn if it’s expensive. So pardon us if we defer you to these wonderfully cute and inventive Polar Ice Cube Trays.
Instead of using the traditional tray, this ice cube maker uses a cup like design. The caveat is that it only makes one batch at a time, but the $28 asking price does includes a set of two molds that makes one Polar Bear cube and one double Penguin cube. Brilliantly the cubes are specifically designed to float as if they were sitting on an iceberg set a draft in the deep ocean. How fun.
Amazon sells the set via a retailer. Just factor in $5 for S&H and they’ll be yours.
