Program Description

Event Details

What is the difference between Light Emitting Diodes and Incandescent Lights? Are UV lights and blacklights the same thing? How does electricity flow, and what does “conduct” mean? Discover the answers tothese questions and more by creating a LED Popsicle Flashlight. Then use invisible ink to write a secret message and use the flashlight to reveal!
