With lots of stretching and reaching toward blue, red, yellow and green circles, some 450 high school students played Twister on 180 mats in what they hope will set a world record for the largest Twister game board.

Sunday's night attempt took place during a conference held over the weekend by North Dakota DECA, a high school business club.

State DECA adviser Kevin Reisenauer, of Bismarck, was confident. "We will break the record."

The students won't know for sure until officials at Guinness World Records review a video of the attempt.

The mats formed a Twister board measuring 4,699 square feet. The current Twister board record was set in April 2005 in the Netherlands, at 2,453 square feet.

DECA, which stands for Distributive Education Clubs of America, aims to improve education and career opportunities for students in such areas as management and entrepreneurship.

One of the biggest tasks was taping the mats together, organizers said.

"There truly is a process to it, and we learned a lot," Reisenauer said.
