There's a lot of emphasis on lateral thinking nowadays - and that reminded me of an example that occurred in one of my high school classes. So I thought I would see if the IronWorks members could come up with the same solution my classmate did.

Here's what happened.

The teacher caught a student making a paper airplane in class. Instead of punishing him, the teacher issued a challenge - IF the student could make the plane fly past a line drawn on the floor, he wouldn't be punished at all. However, if the plane did NOT go past the line, the student would get 3 licks from the teachers paddle.

The teacher gave the student 3 tries. The airplane was a "stunt" plane instead of "jet", so it just flew in a circle on the first try. The second attempt was even worse...the plane actually landed behind the student.

Down to his last try, the student made ONE CHANGE to the airplane's design - and successfully got it past the line.

What change did the student make to ensure the plane would fly straight?
