Initial Wire Preparation and Staged 'Shock'

What happens here

The video begins with an individual on a step ladder attempting to connect the wiring for a ceiling fan. They use a pair of wire strippers to cut and prepare the existing house wiring and the fan's power cord. While performing what appears to be a wire connection, a brief burst of sparks is dramatically simulated (likely using a hidden angle grinder or similar effect), making it appear as if the installer has received an electrical shock. This is a staged event designed to introduce the theme of electrical safety.

Goal: Prepare existing wiring and stage an electrical 'shock' to introduce the topic.
