Der Wasserwirbler...

The Orgone group sells a vortexer that screws onto the faucet.

I'll look into the Vitaliser though. Do you have a link for a company that sells it?
A quick google just now doesn't get me anywhere...do you mean the "Vortex Plus"?

I've seen Weleda products, and commercially prepared Demeter food-products, but I haven't had the luxury of BioDynamic produce as of yet. Apparently a lot of it goes to homes for the elderly and "mentally challenged".
