• This demonstrator is used for science teaching in middle schools and is used to demonstrate the gravitational action between solid molecules.
• Simple operation, strong interest, good verification
• Experiments have proved that there is a gravitational force between solid molecules, and this gravitational force is larger when the molecular distance is small.
• After the two lead posts are bonded and when hanging objects, handle them with care and avoid impact.
• This instrument is composed of a demonstrator, scraper, squeeze trigger and other parts.
