Some are referring to cup stacking as the fastest growing sport in the country. And while we don't really consider it to be a sport, it definitely seems like a sort of impressive hobby for some people!
Cup stacking is exactly what it sounds like. A competitor (or competitors in some cases) take plastic cups and stack them into a pyramid, then quickly collapse them back down. Whoever stacks and unstacks the fastest, wins! There are competitions all over the country for this, with people competing in both singles and team events.
So if you're not really someone who likes to get outside and do more traditional sports, maybe cup stacking is for you!
