**※ Produced at the 100th Lausha Stained Glass Factory in Germany**
**※ pure hand-made craft science toys**
Put the little devil floater into the special bottle, when the hand puts pressure on the bottle, through the principle of Archimedes and the ideal gas law, the floater will move up and down and rotate, it is like in the water ballet~
The Raussing stained glass factory in Schrock, Thüringen, Germany, has a long history of glass making.
In the 157-year history, the stained glass factory has been at the heart of the glass city of Raosa.
The purely hand-made little devil floats, each one looks different, and pieces are unique in the world.
The gap between the devil's tail is not a trick, but the key to its ability to make a splash in the water!
Exerting a handful of bottles filled with cartesian diver by hand to increase the water pressure in the bottle, resulting in a reduction in the volume of gas in the cartesian diver, thus reducing the buoyancy of the water on the cartesian diver when the cartesian When the diver's weight is greater than the buoyancy, it begins to sink. After the hand drains the bottle, the water pressure in the bottle decreases, the volume of the gas increases, the buoyancy increases, and the floater cartesian diver floats.
