Polar Ice Tray
Sure, ice spheres might have lower surface area and melt slower than cubes, thus diluting your drink less, but the main reason we use them is for their looks. And with Polar Ice Tray every sphere is crystal clear. Unlike most ice sphere makers that result in foggy ice, Polar Ice Tray uses a dual-chambered system that separates clear ice from impurities, freezing from the top down thanks to an insulated base (the black bottom component) and thus pushing air out of the ice sphere and into the water below the mold. And for even more stunning drink coolers, try adding a piece of fruit or a flower between the mold to trap it within the transparent ice.
