A group of "slackliners" took their hobby to new heights recently, by walking a line strung between two hot air balloons way up in the sky.
Members of the Skyliners team call this their first completely movable highline.
None of the walkers made it safely across the line, but fortunately they were all wearing parachutes.
The group says, "we'll be going back again very soon to make it happen."
