I just saw a Kickstarter campaign for a "[vortex vessel](https://www.kickstarter.com/projects/mayuwater/mayu-keep-your-water-healthy-with-a-natural-swirli)" that supposedly improves tap water for drinking.

Some of the claims:

* "[Tap water is] stuck in closed pipes where no beneficiary chemical reactions can occur"
* "Toxins from the pipes dissolve into the water, and bacteria colonies flourish in the cracks"
* "Chlorine was added to the water [...] not great for us"

Their product, a jug which causes a vortex:

* "brings water back into [its] natural form"
* "aerates and balances the water with atmospheric oxygen"
* "starts a line of chemical reactions - evaporating chlorine, volatile organics, and other toxins"
* "precipitating metals like manganese and iron so they don't react in your body"
* "stripping away the metallic taste and unpleasant odor"
* "balancing the water's pH level"

Can simple water movement really provide all these benefits? It seems like a ridiculous set of claims.
