Watch: UNI Students Learn Balance Through 'Slacklining' - Like Tightrope Walking, But Not

Have you heard of slacklining?

It's similar to tightrope walking, only the line is not taut. It has slack - thus the name - and moves up and down as the walkers cross it.

Some University of Northern Iowa students have taken up the activity. On April 30, they had strung their lines between trees near the UNI Campanile.

"First of all it's just fun," said UNI senior Eric Atchison, 23, of Sioux City. "It's really great for balance, and it's good cross-training with the other sports I do."

He said he's been slacklining for about six months. He said it helps him relax and clear his mind.

"It requires a lot of focus," he said. "When slacklining you can't be focusing on anything but staying in the middle."
