ELYRIA -- Students at several northeast Ohio schools have helped set a participation record for a cup-stacking exercise that involved more than 500,000 participants from 33 countries this year.

The Chronicle-Telegram in Elyria reports (http://bit.ly/1jjn8jL ) the World Sports Stacking Association notified participating schools that a record number of participants took part in the challenge last week.

Westwood Middle School physical education teacher Tricia Small says the activity mixed hand-eye coordination and physical exercises for her students.

She says the challenge focused on the number of stackers, not the number of cups balanced in rows. The stacking association says participation numbers aren't finalized but definitely beat the previous record, set last year with just under 484,000.

The association has repeatedly partnered with The Guinness Book of World Records on the cup-stacking challenge.
