A simple, memorable way to explore circuits and conductivity
The Energy Ball (UFO Ball) is a simple yet powerful way to teach electric circuits and conductivity by turning students into part of the experiment. This flashing Energy Ball, also known as the UFO Ball, consists of a 1.5-inch sphere with two small metal electrodes. When both electrodes are touched simultaneously, the ball completes a circuit—causing it to flash and emit a strange, attention-grabbing tone that instantly brings electricity concepts to life.
Why Teachers Love the Energy Ball (UFO Ball)
- Students become the circuit: The Energy Ball allows students to act as a human “hook-up wire,” making learning interactive and memorable.
- Instant, visible results: Flashing lights and sound clearly indicate when a circuit is complete.
- No setup required: Completely self-contained—no batteries or external power source needed.
- Highly sensitive activation: Uses a field effect transistor, so even slight conduction triggers the response.

What You Can Teach with the Energy Ball (UFO Ball)
Ideal for elementary, middle school, and introductory physical science classes:
- Open vs. closed circuits: Seeing exactly when a circuit is completed
- Conductivity: Exploring how electricity flows through different materials—and people
- Human body & electricity: Demonstrating that the body can safely conduct electricity
- Circuit pathways: Creating student “circuits” by holding hands or using objects
- Cause and effect: Observing how connections control electrical behavior
Perfect for Group Demonstrations & Events
- Great for whole-class participation: Easily involve many students at once by forming human circuits.
- Highly visible results: Flashing lights and sound make outcomes clear for large groups.
- Ideal beyond the classroom: Works well for science nights, STEM camps, clubs, and outreach events.
Small Parts. Not for children under 3 years.
