Make Giant Ice Balls in your home freezer. Mother nature provided the perfect design to capture water in spheres: Peas in a pod (Edamame in Japan). Spherical ice cubes look extra-cool and keep your drink extra-cold, for longer. Spherical ice melts 80% slower than cube shaped ice, so they won't water down your drink as quick. The ice tray stays upright when filled to prevent spilling. Once frozen squeeze ice out of the mould into your drink.
