Put the floating sink into the bottle, and when the hand puts pressure on the bottle, through the Archimedes principle and the ideal gas law, the float will move up and down and rotate, just like jumping on the water ballet~

The Lausas Stained Glass Factory in the schist mountain of Thüringen (Thuringia, Germany) has a long history of glass making.
In 157 years of history, the stained glass factory has been the core of the glass city of Lausa.
The handmade hand-made floats, each of which grows differently, are pieces of unique crafts in the world.

**principle/**
Squeeze the bottle with the floates of the cartesian diver by hand, so that the water pressure in the bottle rises, resulting in a decrease in the volume of gas in the cartesian diver, thus reducing the buoyancy value of the water for the floating sinkes of the cartesian diver. When the weight of diver is greater than the buoyancy, it begins to sink. After the hand is released, the water pressure in the bottle is reduced. The volume expansion of the gas causes the buoyancy to increase, and the floating sinker cartesian diver rises.
