Puzzle Doble Rueda

The challenge is to extract both balls at exactly the same time. The two gears each have a circular mark on the edge, turn them until the two marks are next to each other. Insert a ball into each maze through the "c" shaped holes in the center of each wheel. When both gears are moving at the same time, a step closer to one gear can mean a step further to the other. Can you solve the puzzle and amaze everyone?
