Abstract: This invention comprises a method for diet and weight control by altering the senses of smell and taste. The topically applied composition hinders the use of the olfactory nerves by either chemical or mechanical means. A further embodiment comprises a scent diffuser that blocks a food's smell. The loss of smell and taste caused by the composition and devices effectively decreases the appetite of an individual, enabling the individual to eat less and lose weight.

Abstract: A modified test tube is provided which can sit on any flat surface unaided by a test tube rack. The modified test tube is an elongate, substantially tubular member having a containment portion coupled to the neck portion. The containment portion has a bottom surface and a closed end. The neck portion is angled relative to the flattened surface and has a mouth. A sloped surface is provided at the interior of the tubular member coextensive with the flattened surface. The bottom surface of the modified test tube enables the test tube to sit prone on any flat surface by itself, unaided by a rack, and the bent neck portion prevents the contents from spilling from the test tube. This design enables the contents within the test tube to be easily monitored without moving the test tube.
