“The Tempo Drop is a borosil glass device in which camphor and ethanol are sealed. The locked-in chrystals react to the subtle changes of weather, before we can experience the weather change ourselves and can therefore be used as a weather predicting device. Clear liquid indicates that bright and clear weather is on its way. Small dots in the liquid indicate foggy weather, and small stars on a bright winter day are announcing snow.” [x]
