Because lead is easily oxidized, the scraper scrapes the lead column smoothly before each experiment, and the experiment is successful. 2. When the two lead columns are docked, try to make the two lead columns consistent in order to eliminate the air between the surfaces of the two columns, so that the molecules are more closely combined. 3. After the two lead columns are bonded and when hanging heavy objects, they should be handled gently and cannot be impacted. Note: Please allow little color difference due to different display or light environment.
