The larger the ice, the slower the dilution rate.  This makes a difference, especially when you are enjoying your favorite whiskey or bourbon. 
 
If you love clear, razor-sharp ice balls, then you need the clear sphere maker. This unique ice ball maker lets you make one clear ice ball, perfect for cocktails or other drinks. The secret is in the mold design, which slowly melts the ice as it forms into a ball, leaving behind any impurities or air bubbles. That means your ice ball will be crystal clear and absolutely beautiful. To use, simply fill the mold with water and place it in your freezer. In about 6 hours, you'll have one perfect clear ice ball. Then just pop them out of the mold and enjoy!
