It all started on paper with an idea and a bottle of water.
"We thought we should come up with a product that's easy for you to run with so the water wouldn't be sloshing around while you're running," said Tyvonda Cooper, a senior at Havelock High School.
The four students were given the task of inventing a product they call SoleH2O. The product makes it easier for runners to stay hydrated without carrying a water bottle or camel back.
"A regular water bottle is hard, and it doesn't have a handle. A camel back is heavier. It's like a backpack. It's a lot more inconvenient," said HHS Junior, Alicia Bess.
The idea behind the SoleH2O is to replace your common 24oz water bottle. It has a retractable bag inside a neoprene casing. While you are running the more you drink, the smaller the casing gets.
The retractable bottle idea came when one student saw a commercial about the retractable water hose. The students submitted the idea to North Carolina State's Institute for Emerging Issues Innovation Contest. While they were finalists in the competition, they didn't get enough votes to take home the prize, but they are not giving up.
"I think we have a marketable product, and I've given these kids my word, we're going to take it to market," said Carr.
