Seamless ice-spheres for superior whiskey-rocks

Using a sphere of ice (as opposed to a cube) in your whiskey-rocks is nice because the round ice melts more slowly than the square stuff (better surface-area/volume ratio). Now a Japanese company has introduced a mold for making a perfect, seamless ice-sphere:

Taisin has introduced a mold that seamlessly creates a perfect sphere, no chipping and shaving required. Simple place a chunk of ice into the metal press and, as it melts, the device will close around the ice forming a ball, which is then released by the flick of a switch.

The Ice Mold, available in 55, 65, 70, and 80mm mold sizes, can make 30-40 ice balls an hour.

Spheres of ice are preferred by serious on the rocks drinkers because the reduced surface size means that the ice melts at a slower pace, keeping your drink
