Hello! If you're heard of directional freezing, learned to make clear ice in a cooler or in a thermos, or purchased clear ice cube trays, that information all came from me, Camper English, writing here on Alcademics.

My big discovery of what became known as directional freezing was in 2009, and now it's used all over the world in smaller cocktail bars, in homes, and in the form of many commercial ice cube trays (none of which are owned by me, sadly).
