Freediving in low-visibility conditions? Doing a night dive on scuba? Wish you could see your dive line easier? Saint James, MN-based Fire Forks Unlimited may have a solution: rope that glows in the dark.

While the company was showcasing the rope at the DEMA Show in Las Vegas this week, Fire Forks had released it into the market last March. The company charges between $1 per foot and $2.90 per foot, depending on the thickness, according to a Fire Forks brochure.

And you don’t need a sunny day to recharge them ??????? “UV rays charge the product even on cloudy days,” the brochure reads.
