Without forethought, Kari Byron has trained to be a MythBuster since she was a kid. By the age of 5 she was setting up experiments to test on her sister and using dolls as crash test dummies. Luckily for her parents, they always caught her right before little sister took a ride down a laundry chute or was the subject of an "around-the-world" attempt on the playground swings.

After graduating from San Francisco State and traveling the world, Kari began her career as an artist, working in sculpture and painting and holding successful exhibitions at some of San Francisco's leading galleries. "Artist" was only one of many hats she wore while searching for her place in the world. Her sculpting skills and love for odd jobs soon led her into the field of model-making and toy-prototyping, which led to a job with Jamie Hyneman at M5 Industries. It was at M5 that Kari got her first big break with the MythBusters team.
