The Fact Fly's One Big Question How can a solid wall be totally invisible? Join Lauren, the high-energy Fact Fly, and their brand-new, fuzzy-green friend, the Curious Caterpillar (CC), as they dive into the hidden world of atoms to uncover the secret of glass! From "messy" atomic crowds called amorphous solids to high-speed light sprinters called photons, this episode explores the material science that makes our windows work. You’ll discover why glass is actually a "frozen liquid" that is too busy being disorganized to catch any light—and learn how nature uses the same trick to trap insects in golden amber for millions of years! From the 3,000-degree "Mega-Melt" of beach sand to the mystery of why glass blocks some "ouchy" sun rays but not others, this adventure reveals why we can see through glass. Perfect for young scientists, future engineers, and anyone who wants to see clearly how the world works!
