Beschreibung
Zusammenfassung:	A demonstrator of density and buoyancy comprises a shell, a hollow transparent cylinder, a refrigerating tube, a heating tube and a plurality of floating small ball. The hollow transparent cylinder which is hollow and transparent is arranged in the shell. The refrigerating tube is arranged at upper part in the cylinder, and the heating tube is arranged at the lower part of the cylinder filled with purifying water inside. The floating ball with different weight and buoyancy is in water. The utility model has simple structure, can directly the relationship between buoyancy and temperature, and is a good display device about density and buoyancy in the process of adolescent learning physical knowledge.
