High wire artists cross world's biggest waterfall

Two daredevil high wire artists have successfully walked across the world's biggest waterfall - Victoria Falls in southern Africa.

Lukas Irmler, from Germany, and Reinhard Kleindl, from Austria, spent two years training for the massive challenge.

They both managed to cross the 100-metre long line and they had a safety rope in case they fell.

Victoria Falls is on the border between Zambia and Zimbabwe. It's known as 'The Smoke that Thunders' by local people.

Watch the clip to see Lukas and Reinhard in action and hear them talking about how they did it.

This act was done by professionals so do not try to do anything similar yourself.
