The New Zealand Black Stacks - a team of competitive cup stackers - have left for Germany to compete in the world sport stacking champs.
Black Stack Caleb Mills, 15, is a home-schooled chicken entrepreneur and stacking enthusiast who has partly funded his overseas trip by selling free-range chicken eggsto local businesses in Rotorua.
Stacking was invented in the 1980s and is good for growing your brain and dexterity, Caleb said.
The sport involves stacking and unstacking a set of cups on a mat as quickly as possible and mere fractions of a second make the difference between winning and losing.
Caleb lives with his family in the back of beyond near Murupara and says stacking is a good sport for kids not so talented at traditional outdoor sports.
