With the objective of contributing to make significant the scientific learning, this work suggests a simple and low-cost experiment to demonstrate electrostatics knowledge studied in High School. The experimental proposal has yet the concern of focusing the content, linking it to daily technological elements. Doing that, and due to the practical interest it can arouse in student, we presented the operation of an idealized Lightning Rod to apply in electrostatics school knowledge and to show that the same one can have an important day by day usefulness and it cannot be a turned off abstraction or distant from the reality.
