Star Projector Jar
Professor O will help you learn: A small light inside a pricked foil jar throws tiny beams onto the walls, showing how light travels in straight lines and turning your room into a peaceful planetarium.
⚠️ Use a battery tea light, never a real flame, inside the jar. An adult should make the holes in the foil.
Play through the project step by step, with narration read aloud.
