RHINELANDER - When a cup is flipped upside down, it becomes a part of a growing sport known as Speed Stacking.
"When you do speed stacks it works both sides of the body, both sides of the brain," said Ambassador of Speed Stacks Becky Barker.
Barker used to teach the sport during her time as a P.E. teacher.
"It was my favorite lesson plan so when I retired I bought my own cups," said Barker.
She still teaches the sport in schools as a special guest, and at events like the one at Calvary Baptist Church Thursday.
Ten-year-old Aubree Dumpprope learned to speed stack at school last year and wanted to get some more practice.
"This year I got faster and faster I got a better time here," said Dumpprope.
Thursday Aubree and her friend Mikayla Kurth learned some new techniques.
"I learned how to do 10s, 10 cup stacks," said Kurth.
The girls also have a chance to be part of a world record.
Thursday people all over the world stacked at the same time for 30 minutes and hopefully were part of a group that had more people than in any year before.
"Every year we try it, every year, this is maybe our third year," said Barker.
Barker says each year they have taken part, the record has been broken.
This year Aubree, Mikayla and the rest of the group at Calvary Baptist are hoping to stack their way into the record book.
"That would be awesome, I would love to be part of a record book," said Dumpprope.
All locations will submit their numbers and in a few weeks we will find out if they broke the record.
