The GMX Ringmaster shows what magnetics can do to the taste of different liquids/drinks, such as coffee, tea, grapefruit juice, grape juice, wine--for the most part liquids that have a slightly bitter taste.
Please Note: Pour the liquid into a small glass, taste it, then place the liquid on the south attracting side of the ringmaster (label up). Stir the liquid with a non-metallic stir stick and let them taste it again. There is a real difference. Use two different glasses for the test (one for the non-treated and one for the treated) that way you can go back and forth to be sure of the difference.
