DIY Energy Tube: Light it Up!

Home: California

Join us for a hands-on activity and learn to build an energy tube using simple materials: construction paper, tape, clay, alligator clips, a 9V battery, and multi-colored LED lights. Learn how to complete a circuit using your body—and experiment with other everyday objects like water, utensils, cans, and even food to test what conducts electricity! This interactive project introduces the science of open and closed circuits, conductors and insulators, in a way that's visual, memorable, and fun. Kids and families will create their own circuit stick, then watch it light up when they become part of the circuit themselves. It's a one-of-a-kind STEM activity that brings science to life.
