Now, that really would be magic water or maybe magic ceramic beads. Imagine having ceramic beads floating in or being supported by water. I happen to have one of those ceramic beads (actually the size of a regular marble) and try as I might, it keeps sinking to the bottom of the container.
"Given that the only ceramic involved is a bead that floats around in the water."
Yes, add lime to water to make it alkaline. Easy peasy. How do you make it alkaline without adding anything else? You cannot use any of those fancy ceramic thingies either. They are just a hoax you know. They are fake balls in the water to make people think something magic is occurring.
