In the new series, the kids and celebrity reactors not only watch and respond to viral videos, but participate in epic showdowns where they take on a challenge based on a video they just watched. Whether it's a basketball trick shot or the world record for fastest clapping, the challenges bring a physical element to the show that's never been seen in the online version.

In its three years since launching online, the React franchise has garnered over 1 billion video views and over 10 million subscribers. The success of Kids React has yielded spinoffs Teens React, Elders React and YouTubers React.
