Tempo Drop Storm Glass Weather Forecaster

Storm glasses are weather forecasters that have been used by navigators as early as the 19th century. It is made by sealing camphor (camphor extract) and ethanol in a glass tube, and it was used by observing the crystals that occurred in response to climate change. It is also installed in the Nautilus that appears in Jules Verne's novel, "Twenty Thousand Leagues Under the Sea." With the development of science since then, it has become clear that there are still many mysteries about the crystallization phenomenon, and the details are still under study. Though you may not be able to use it as a predictor in modern times, you can enjoy the appearance of crystals that change day-by-day with our Tempo Drop Series just like the scenery changes with the seasons.
