Mischievous Static Ball/Mischievous Static/Static Rolling Ball - Science Museum Exhibits Program
Science Behind It
Frictional electricity generation
The redistribution of charges caused by friction, as well as the redistribution of charges caused by mutual attraction of charges, especially because matter is composed of atoms with negatively charged electrons and positively charged atomic nuclei. Under normal circumstances, the positive charge of the atomic nucleus is equal to the negative charge of the electrons, and the positive negative balance is therefore not important. However, if electrons leave their orbit under external force, resulting in an unbalanced distribution of electrons, for example, frictional charges are the process that leads to an imbalance between positive and negative charges. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. When two different objects come into contact and rub against each other, the electrons of one object are transferred to another object. Due to the lack of electrons, the object becomes positively charged, while the other object gains some negative electrons and carries negatively charged static electricity. Exhibition items description
The base of the exhibition items is made of resin material with air added, and a glass cover is set on the base. Inside the glass cover are white plastic balls.
source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Remind participants to rotate the base to generate static electricity through friction between the base and the plastic ball. After a period of time, you can see the ball gently floating up.

How to Operate
① Participants rotate the bottom of the glass cover to generate static electricity through friction between the small balls on the exhibition base;
② Watching the ball gently float up;
③ Bring your fingers close to the glass cover and you can see the ball avoiding your fingers;
