Well Aqua Plate (2005) |
| The
Well Aqua Plate consists of a thorium-containing ceramic powder sandwiched
between two sheets of plastic. Among other things, the plate is intended
to eliminate odors in cars and relieve stress while driving. It can also
be used in shoe closets to eliminate odors, or in refrigerators where the
manufacturer claims it will help preserve food longer. The plate is
washable and is said to last three to five years before replacing. You
would think it would last longer given the ten billion year half-life of
thorium-232. Made by Nakano Tec Co., Ltd., |
