It's called sport stacking or cup stacking or speed stacking or just stacking. The goal of the game is to stack special cups in a specific sequence as fast as you can.
Candice Willett learned how to stack a few years ago in an after school program.
"They had me do it with one hand and then they had me do it with two hands," the 17 year old explained.
She started with one hand then learned how to stack with two hands even through her left hand is partially paralyzed.
Candice's grandmother Jenny Wright said, "Next thing I knew I was being invited to a championship thing she was in and she won one of the championship shirts."
Her success surprised Wright because Candice was born with severe heart and lung problems.
"There's a lot she's had to overcome," she said.
Candice has had four strokes.
"Her speech disability is caused from the strokes," her grandmother explained. "Her larynx is paralyzed."
Her stilted speech is one reason Candice says she has been bullied. She's become an advocate for kids who are bullied for whatever reason.
"Now I'm one of them," Candice said.
Her aunt helped her make a facebook page to spread the word to stand up and speak out.
"I want bullying to end," Candice said.
She wants bullying to end.
And she wants to keep stacking.
"She's just a resourceful little girl who takes what's been given her and thanks God for it and goes with it," Wright said.
She's a little out of practice but Candice can still complete the stack in about 25 seconds; 18 seconds is her record.
Does her grandmother stack?
"Oh no. I don't even understand the process," she said with a laugh.
But she understands that Candice has made progress way beyond what her doctors expected.
"It's a miracle. She has been called a miracle child by every doctor who has seen her," she said.
Candice Willett is a champion speed stacker and a champion for those who have been bullied.
