Fun Science Storm Glass Cloud

Weather forecast ornament

Nobody knows when it was invented, by whom, or how it actually works. It was made popular in the 1860s by the captain of the ship that took Charles Darwin on the trip that helped him form his theory of evolution and it couldn't but find its place in a land like Japan, where everyone obsesses over the weather. Its name is storm glass and with the Fun Science Storm Glass Cloud, you can get it in a cute cloud shape – cute being, of course, another thing the Japanese obsess about!

Made of borosilicate glass that is more sensitive to thermal changes than any other common type of glass, the Fun Science Storm Glass Cloud sits comfortably on its wooden base and changes density depending on the weather. Reading its measurements is easy, since its contents (which include water, ethanol, natural camphor, and a couple of chemicals) create only a handful of different conditions. And even if you'd rather get your weather forecasts from TV meteorologists, it is also great as an original decorative item!
