TOKYO (AP) — Australian canoeist Jessica Fox found a perfectly stretchy, waterproof material for a boat repair at the Tokyo Olympics: a condom.

Fox, who won a bronze medal in women’s kayak slalom and gold in the canoe slalom, posted a video on social media this week of someone making repairs to the nose of her boat.

First, a gooey carbon mixture is applied before the condom is used to secure it in place.

“Very stretchy. Much strong,” the caption reads.

The 27-year-old Fox is the world’s top-ranked paddler in canoe and kayak and won the first women’s canoe slalom race in Olympic history.
