Going Deep with David Rees (2014)

S1E1 How to Make an Ice Cube

David has grown weary of dull, subpar ice ruining his drinks. When he prepares a cocktail at home, he envisions a glass brimming with ice that sparkles like diamonds, specifically in perfect cubes. Follow David on his quest for knowledge, as he seeks guidance from icemakers, ice sculptors, ice harvesters, glaciologists, and wise Buddhist monks. After this journey, you'll look at freezing water in an entirely new way.
