In a recent interview Anna Kendrick has apologized to parents. She says  "Dear parents that I meet, I know that sigh, and before you even say it, I'm very very sorry that your child won't stop doing Cups." She added that she is aware of some kids who obsess over it.

I'm going to add to that by sharing the tutorial video of how to play cups, with a cup.

Check out the video and see if you can master it!
