Applause sign

When you go see a show, like a play or a TV show, there's a sign that tells the audience when to clap and cheer. It's like a big sign that says "applause" or has a picture of people clapping. This helps the audience know when it's time to show their appreciation for the performers. It's like a reminder so we all cheer together and let the performers know we liked what they did. It's kind of like when your teacher tells you to raise your hand if you know the answer, it helps everyone know what to do at the same time.
