In this episode, we discover why you might have thought you saw a ghost. We found out that many cultures, even if they are far apart, have tales about ghosts or spirits. We looked at ghosts from a science perspective and learned that sometimes our eyes and brains play tricks on us, like seeing things that aren't really there. We also talked about how you could design an experiment to find out if the ghost your friend saw was real. Plus, we dived into the magical world of rainbows, the buzz of mosquitoes, and the mysteries of our noses. Did you know mosquitoes really like Type O blood and are drawn to carbon dioxide and sweat?
