What materials are needed for the static electricity experiment?

The selection of materials in this option is particularly suitable for demonstrating static electricity due to their conductive and non-conductive properties. Salt and pepper can be effectively used to illustrate how static charge can attract or repel small particles when a charged object, such as a plastic spoon or a plastic bag, is introduced into the setup. The dish cloth can be utilized to generate static charge through friction when rubbed against the plastic materials, creating a clear demonstration of static electricity principles. The addition of a black piece of paper is optional but can enhance visibility, helping to better observe the effects of the static charge on the mixture of salt and pepper.

This combination of materials allows for an engaging experiment that highlights the behavior of static electricity and offers visual and practical learning opportunities. Other options either involve materials that are not as effective for illustrating static electricity concepts or do not create the same level of interactive engagement.
