Something tells me there are a few Maker's Mark Ambassadors here on StraighBourbon. Maker's sends their Ambassadors holiday gifts each year and for 2010, Maker's Mark has delivered a nice plastic ice ball maker for a spherical shape which will ensure less surface area in your near "perfect" ice cube, it won't melt as slowly giving you optimum Bourbon drinking moments..and not the water.

Anyone used theirs? Here is a picture of it and more info on this link - ice ball maker

Or you could use these in place of snowballs for snowball fights...jk!
