A Baltimore County family is heading to a world championship next week, where they will represent the United States in a cup stacking competition. It's called sport stacking, and speed is everything.Next week, Deana Wilson, her 11-year-old son, Colby, and her mom, Donna, are heading to Spain to compete against stackers from around the world."I am ecstatic to go to Spain. I cannot wait," said Donna Harris.The family will represent part of Team USA in the World Sport Stacking Championship. It's their first international competition, but they've competed all over the country."I love it. I love traveling. I love being able to compete with something that my son can do with me. I'm not the type of person that's going to do baseball or football or anything like that. I'd rather be indoors, stacking cups," Wilson said."(Deana) and I will try to beat (Colby). We get a head start, (but) he still beats us. But we're very competitive. That helps us and helps him to get better," Harris said.Wilson and Harris started stacking cups four years ago to keep up with Colby, who got them into the sport. He's earned titles for his speed."I like that I get to compete with other people, especially from other countries, and I just like to be competitive," Colby said.To help the family get to Spain, Wilson's boss, the owner of Caton Auto Clinic, is sponsoring their trip."It's unbelievable to watch what they can do. This little kid is phenomenal," said Ken Steinbach, owner of Caton Auto Clinic.Stacking cups takes family bonding to a new level with a skill that Harris admits she never thought she'd learn later in life.​
