Instructions
1. Balance adjustment before the instrument is used: Before the instrument is used, the lever should be basically horizontal, otherwise it is necessary to adjust the horizontal balance of the lever. When adjusting, lift the seal cover, level the cover end with one hand, and screw the slider with the other hand to make the lever level, then put down the seal cover and press it hard to make it fit well with the transparent cylinder (when closing the cover, it should be noted that the rubber seal ring sleeved on the seal cover mouth should not be misaligned), and then place it on a horizontal table to prepare for the experiment.
2. Carry out the experiment: turn the instrument air valve to "ON", connect the air valve with the air extractor with a hose, hold the air cylinder with one hand and extract air with the other hand (at the same time, observe the changes in the balance of the lever). During the continuous air extraction process, we will soon find that the foam column sinks and the tilt angle of the lever gradually increases. When sufficient changes are observed, stop pumping, turn the air valve to the "off" position, and the experiment is completed.
3.Conclusion: The experimental phenomenon tells us that the gas will generate buoyancy on the object immersed in it.
