the design of the experimental apparatus with water into a water storage tank of the storage on the part of the transparent material is made to be a structure installed in a water tank, and the the lower part of the transparent material is made for the distribution of the water tank, the pressure pump to the use of water storage tank of water in a water tank, a small drug, can be in the free state. in the water tank, and a water tank on the water, and out of, the counterclockwise rotation is ubc1cuc0ddud558 natural state, a vat of water for me water tank for oil or natural state is when the counterclockwise rotation in a water tank, the water tank, and the use of stone in the occurrence of the external can be simply observed. therefore, according to the design of experiments for the school, and a lot of people in the township. the former is the body caused by the rotation of the simple experiments can be done.
