Of course, he doesn't seem to predict ahead of time.(this is how a bottle of magic! The principle of "descendants of" Weather induction glass to do some research.Ph. Anne Marie Helmenstine think storm bottle based on the influence of atmospheric temperature and pressure on the solubility of work, but she was not totally sure what ingredients cause of the change.There are other scientists retort that the bottle is sealed, unable to effectively perceive air pressure and temperature, and then doubt the effectiveness of storm bottle of weather forecasting.View,put forward by the new storm bottles of the surface of the outer wall and internal mixture interaction that allows the formation of crystals? Some view the current role of glass material itself and quantum tunneling through as to a certain extent will affect the storm bottles of rendering result. Less the number of papers on the above experiments, some argue that the forecast basically, caused by storm bottle temperature is the only factor that affect the growth of storm crystal bottle. Features: drop type glass containing liquid is, very strange objects to repeat the crystallization of various expressions, depending on the weather changes. >Include: 1* storm glass 1*Solid wood base 1*Instructions 1*Elegant gift box Small-Storm Glass Dimensions 2.3 x 2.3 x 4.7in
