Why does spring water come out the ground continuously? How does a ship bear large loads while sail on the sea? How did Archimedes test and figure out the material of pure gold? How does a magician put a needle through a ballon without explosion? That is due to some special physical features such as pressure, buoyancy, density and surface tension, etc that the liquid has. And which presenting a dominated role is primarily based on the working condition specified. Thus establishing a variety of experimental method and kit is still required to access the satisfied solution for individual demand. In this subject, the  proposed experiment is intended to familiarize the user with the liquids characteristic, and seek practical possibility for further application.


  1. Pressure experiment-communication tube, Venturi tube, lateral pressure, upward pressure, siphon, Pascal’s principles.
  2. Buoyancy experiment.
  3. Experiments of surface tension and capillarity of glass.
  4. Density experiment – Archimedes’ principle, solid density.

The buoyant force for a submerged object could be directly measured by reduced weight of object in the water. Here W0 indicates initial total weight (volumetric cylinder + submerged object + liquid), W1 means residual total weight after the liquid volume Vin is discharged out by immersed object.

Experiment—Water pressure observation

By way if air membrane immersed inside the given depth of liquid in right column, the compressed air from the membrane, connected to U-shaped tube, will induce different water-level and the difference might be amounted to hydraulic-pressure distributed at both side. Here the liquid density d and liquid-depth h are found to be both important parameters determining static local pressure P=h x d
