Specification: Item Type: Cohesion Demonstrator Kit Material: PVC How to Use: 1. Put the metal column into the scraper and turn it gently and evenly in the clockwise direction to expose the new metal body. 2. The two sections of metal column flat butt, the two ends of the hard press, slightly reverse rotation, you can stick into one. 3. Hanging it on the stand with a string. At the top, the rope at the bottom can be used to hanging the right amount of weight. 4. A basin of sand can be placed at the bottom of the demonstration to accept heavy objects accidentally dropped due to the experiment. 5. Experiments show that there is an attraction between solid molecules, and this attraction is larger when the molecular distance is small.
