What did daedalus invent to help them escape the labyrinth?

Daedalus invented a pair of wings made from feathers and wax to help himself and his son Icarus escape the Labyrinth. He designed the wings so they could fly over the walls of the maze, avoiding its deadly traps. Daedalus cautioned Icarus not to fly too high or too low, but Icarus, overcome by the thrill, flew too close to the sun, causing the wax to melt and leading to his tragic fall.
