May as well let the gobbledygeeks hang themselves with their own definition:
"The best quality water has a unique molecular structure that can be observed (when frozen) as balanced, geometric crystals. Structured water has properties that are particularly important for life especially as an agent for hydration and detoxification. Naturally, this is the best water to consume, however it is not always easy to come by.
Fortunately, damaged water can be restored in a number of ways: for example, by undergoing a “phase change” through the process of evaporation, condensation, or freezing. Water’s “memory” is cleared by the phase change and the water is restructured. Other instruments and expensive, man-made devices such as ionisers and KIVA lights have also shown improvements in the properties of the treated water. However, an enormous breakthrough has occurred with the creation of TC Energy Design glassware, whose unique shape enables water to restructure itself - within minutes!"
