The user can predict the weather by looking at the solution in the bottle. The solution in the bottle is a mixture of several substances. This unique formula was invented by (Robert Fitzroy) the British Navy Lieutenant. Admiral (Robert Fitzroy) accompanied （Charles） to explore between 1834 and 1836. (Robert Fitzroy) In addition to being a navy, he is also a pioneer in meteorology. As a weather observation device, The biologist （Darwin）, This equipment is also used to assist in maritime navigation. The weather bottle can still be used as a beautiful decoration as the external temperature shows a change of crystal. It can also be used as an interesting scientific textbook to learn the configuration and crystallization behavior of the solution. ②〖STORM GLASS PRINCIPLE〗 The change in crystallization in the bottle is mainly due to the fact that the solubility of the solution changes with temperature in order to control the continuous nucleation during the high-speed growth of the crystal. When the temperature changes, crystals are precipitated, and the rate of change in temperature affects the growth size and structure of the crystal. These factors add up to the beautiful changes in the crystal form of the bottle. ③〖STORM GLASS SIZE〗 Package size：6.1*3.8*3.6（ln） weight：0.3（kg） Wooden seat length * width * height：2.5*2.5*0.78（ln） diameter：2.3（ln） Bottle height：4.5（ln） ④〖CHRISTMAS-THE MOST IDEAL GIFT THANKKSGIVING〗 Give to children Giving to father and mother Give to a lover Give to friend
