Mythbusters is a show where people called "mythbusters" test to see if things people believe are true or not. In the 2008 season, they had episodes like "NASA Moon Landing", "Pirates of the Caribbean" and "Flying Car".
They would do experiments to see if these things are true or not, like going in a pool to see how deep they have to dive to simulate the moon's gravity, or making a car with wings to see if it can fly. They also use things like explosions and robots to test things that are dangerous or hard for people to do.
They explain everything they do and why they are doing it, so people can understand how they came to their conclusions. They also show cool slow-motion footage of things like explosions or crashing cars, so people can see what happened in detail. It's a really fun and interesting show!
