Discover the science behind glow-in-the-dark paint with Emily Calandrelli, an MIT engineer and host of "Emily's Wonder Lab." This educational video explores the properties of ultraviolet light, commonly seen in black lights, and explains its interaction with phosphors found in highlighters to create fluorescent colors. The step-by-step guide includes creating homemade glow-in-the-dark paint using simple household items like cornstarch and highlighter ink. Perfect for enhancing science curricula, this experiment demonstrates concepts such as light wavelengths and energy absorption, aligning with STEM education goals. Additionally, the content is tied to Emily's best-selling "Stay Curious and Keep Exploring" book series, promoting a hands-on approach to scientific exploration.
