The subject is shown an upright bottle or glass with a water level marked, then shown pictures of the container tilted at different angles without the level marked and asked to mark where the water level would be. Piaget and Inhelder developed the test as part of their work on child development.
The blue bottle experiment illustrates this principle of interacting reactions with different rates. [4] The blue bottle experiment requires only three reagents: potassium hydroxide solution, dextrose solution, and dilute methylene blue solution. These reagents are added to a flask, mixed, and the flask is stoppered.
Example: A helium balloon in a moving car. When increasing speed or driving in a curve, the air moves in the opposite direction to the car's acceleration. However, due to buoyancy, the balloon is pushed "out of the way" by the air and will drift in the same direction as the car's acceleration.
When the valve is opened, the smaller balloon shrinks and the larger balloon expands. The two-balloon experiment is an experiment involving interconnected balloons. It is used in physics classes as a demonstration of elasticity. Two identical balloons are inflated to different diameters and connected by means of a tube.
The global horizontal sounding technique (GHOST) program was an atmospheric field research project in the late 1960s for investigating the technical ability to gather weather data using hundreds of simultaneous long-duration balloons for very long-range global scale numerical weather prediction [1] in preparation for the Global Atmospheric Research Program (GARP).
I have not as yet been able to discover the reason for these properties of gravity from phenomena, and I do not frame hypotheses. For whatever is not deduced from the phenomena must be called a hypothesis; and hypotheses, whether metaphysical or physical, or based on occult qualities, or mechanical, have no place in experimental philosophy.

Jean Piccard (left) with his brother Auguste (right) during World War I [7]. In 1935 and 1936, to reduce weight and thus enabling a balloon to reach higher altitudes, plastic balloon construction began independently by Max Cosyns in Belgium, Erich Regener in Germany, and Thomas H. Johnson and Jean Piccard, then at the Franklin Institute's Bartol Research Foundation in Swarthmore, Pennsylvania.
