There exist some ice-trays that instead of having slots for 10-12 large standard-sized ice-cubes, has slots for dozens or even over a hundred tiny ice-cubes. It might seem absurd, but they’re actually a good idea. Having a lot of small ice-cubes means the ice has a lot more surface-area, so more ice touches the liquid, and thus chills it faster. This is why some drinks use crushed-ice. Of course, “There is No Free Lunch™”, and the cost for this faster cooling is that the ice melts faster.
