Clear-ice directional freezing box

Freeze crystal-clear ice from the top down in a thick-walled box

Bar-clear ice is not about boiled or filtered water: it is about which way it freezes. In an ordinary tray the water freezes from every side at once and traps air and minerals in a cloudy middle. This box has 5 mm air-filled walls and stands on feet, so the cold can only get in through the open top. The ice grows straight down and pushes the bubbles ahead of it, leaving a clear block on top and a small cloudy plug at the bottom that you lift out before it freezes. Cut the block into cubes or spheres with a bread knife.
