VIDEO - It is a colorful way to add some pep to your step.
Color runs are all the rage right now.
Joggers and walkers are caked in a tsunami of brilliant powder.
"You look like a giant ornament," said runner Rachel Suddeth. "It's fun!"
An event scheduled for this summer in Oklahoma City is billed as "10,000+ pounds of colorful food-grade cornstarch transforms you into a vibrant rainbow."
"They just blast you with these colors," said runner Leila Adlamini. "Everyone gets together, and you try to get blasted in the face completely."
But, what many don't realize - corn starch, under the right conditions, can be highly flammable. We recruited the help of the Edmond Fire Department to show how easily a cloud of colorful dust can burst into a ball of flames.
While the flash fires are rare, it has happened.
Just last summer, the fun turned to life-threatening fear at a color run in Taiwan.
"500 people were burned, 11-12 actually died," said Edmond firefighter Jacob Stangl. "It was from this. They used a ton of powder. It's still unknown, but they think it was a cigarette. Something ignited it."
