Join the Sci-Squad, a goofy group of superheroes who use their interest in science to learn new things about the universe. In today's episode, the Sci-Squad meets a ghost! But don't worry, there's some special effects trickery going on here. Our heroes find out that the specter is really just a Pepper's Ghost, an old theatrical device that works like a hologram! This resource includes black and white printable sheets and a color version for projecting on screen. Look for demonstrations of a Pepper's Ghost on YouTube. Perfect for a fun Halloween science activity!
