Ice Rocks is a product line from Canada that is one of the unnecessary products, not to mention one of the most blatant examples of overpackaging, ever. The company sells molds that are filled with water and sealed, ready to be frozen upon purchase or delivery. In other words, they are individually prepacked ice cubes.
What is the point of this? To have "fresh" ice? I have no idea how much these cost, but rest assured that it isn't worth it. If the tap water is too unpalatable to drink in your neck of the woods, buy bottled or, better yet, distilled water and use it to make ice cubes. It will save both time and money.
The company is also working on a product called "Ice Kids," which "[explores] the possibility of putting secured ice cubes, made specifically for children, on the market."
