Electrical facilities
There should not be too many appliances in children's rooms, and floor-standing appliances should be avoided to prevent electric shock accidents after children trip. Put the electrical appliances back to a safe place immediately after use, such as electric iron, electric kettle, etc. All sockets that children can reach should be covered with special plastic covers. Clean the mobile power socket immediately after use, and don't put it out of the reach of children. Household appliances should be placed as far away from places where children often play and move.

This is the igniter in the lighter. Naughty, you may have done it. Chase a little girl with this and electrocute her. Yes, this thing is also this action. Catch up with your baby and electrocute him, and he will know what it's like to be electrocuted. What you said is a theory, which is unforgettable.
Thousands of earthquakes
With a new dry battery with an electromotive force of 1.5V, several wires, several switches and a fluorescent lamp ballast (the ballast is constructed as an inductance with a large self-inductance coefficient), the voltage is definitely lower than the human safe voltage, but people who come into contact with it can feel the feeling of electric shock. A treasure is only 200 yuan, so I suggest starting with it.
tiger
The electric tiger is an invisible tiger living in wires. It's best for grandma to tell this story. She was convinced by her actions and expressions, and naturally she dared not touch the power switch.
Safety warning education
The above content is just a preventive way, and it can't really let children know what electricity is and why people get an electric shock when they touch it, but the disconnected wires or switches are fine. Therefore, safety warning education is really important.
