A rod of steel has a line painted on it from one end to the other. It is then twisted in the middle so that the line is half on one side and half on the opposite side. The line is painted only as wide as a quarter of an ant's width. These ants are intelligent and they are told that they must remain on the line or perish. The ants are placed at either end of the rod and told to go to the other end of the rod where they will be fed in safety. If they meet each other, they will both be killed. How do the ants resolve this problem and achieve their goals?
Clues:
1. The rod was solid and could not be made hollow.
2. The ants could not avoid each other if they were both on the line. They could not jump over each other.
3. Both ants were fed and neither died.
4. The rod was not suspended or spun round.
