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.
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.
