What is laughter?

Have you ever noticed how hard it is to stay quiet when someone else starts giggling? Even if nothing funny happened, you just burst out laughing too! But what exactly is laughter, and why is it so catching? Join Mira and Finn on an undercover science mission to find out! In the 1990s, a psychologist named Robert Provine became a "laugh-detective." He secretly listened to 1,200 laughs in shopping malls and made an unbelievable discovery: only one out of ten laughs actually followed a joke! So, what are we laughing at? It turns out, laughter is like a secret code or an invisible string that connects us. Our brains use it to tell our friends, "I like you, and we are safe!" You are actually thirty times more likely to laugh when you are with other people than when you are all by yourself. Plus, did you know that animals laugh too? Get ready to learn why chimpanzee laughter sounds like a panting handsaw, and how scientists discovered that tiny rats giggle when they get tickled! Tune in to uncover the amazing science behind your smile!
