Product Principle:

Two different metal plates (such as copper and aluminum) are connected to a sensitive ammeter. When the hands are placed on the two metal plates, electrons from the aluminum plate will move towards the copper plate. As a result, current will flow through the connected wire and cause the ammeter to deflect.

Gameplay Points:

Simply by placing your hands on the two metal plates, the ammeter will deflect, indicating the presence of electric current. Try wetting your hands and repeating the process. Children can do this activity together to see whose electric current is the greatest (the greater the deflection of the ammeter pointer, the greater the current generated). It’s important to regularly clean the two metal plates to prevent oxidation and loss of effectiveness.
