Soap bars are the wrong shape, in that they are thinner in some dimensions than in others. As a result, they are likely to wear out unevenly to the extent that they break in half, at which point they dissolve faster due to their increasing surface area. A sphere would minimise the surface area, but
it isn't feasible for soap as it would be very slippery. A regular dodecahedron has relatively little surface area and faces, so it would be more likely to wear evenly and slowly. However, it would still be tempting to place it on the same surfaces, leading to unevenness. This could be avoided by piercing each face deeply with a number of dots to form a die. After each use, the soap could be placed back on the dish with the next number upwards, until the twelfth face is uppermost, at which point the process begins again. [link]

Ever heard of soap on a rope? |
