In a hair-raising, electrically charged science lesson, Year 4 used the Van de Graaf generator to understand the principles of electrostatics. The generator applies a charge to its dome and anything else in contact with the dome. If the object is a pupil, they obtain a net surplus of charge (be it positive or negative), which is especially noticeable with hair, as each individual strand is repelled from every other and from the scalp.
