Millie Bobby Brown and Maddie Ziegler are doing their part to make the world a better place!

The Stranger Things star and the Book of Henry actress were both nominated to take on the #ChooseKind challenge, in which you name different ways to be kind in 10 seconds.

Maddie was nominated by her Book of Henry co-star Jacob Tremblay, and Millie was nominated by Maddie.

The simple yet powerful movement was started in collaboration with Jacob‘s upcoming movie Wonder, which tells the incredibly inspiring and heartwarming story of August Pullman, a boy with facial differences who enters fifth grade, attending a mainstream elementary school for the first time.

In her video, Millie explains how you can donate to Hurricane Harvey relief and even gets a sweet kiss from her dog Dolly – see, it’s contagious!

Millie then nominates Hailee Steinfeld, Noah Cyrus, and Kaia Gerber, while Maddie nominates her sister Mackenzie Ziegler and Lilia Buckingham.
