In their earlier grades they had always joined each other on the playground swings but after Albert Ray convinced Al that if they moved the playground swing fast enough and high enough eventually the swing would make a loop and they would be the first in school to make a loop on the school swings. So each day they would make the swings go as fast and as high as they could. When the day came that Al went too high and the swing stalled and fell straight down; he held on for dear life as the fall from 15 feet high that broke the swing seat and one of the chains holding the seat. The teachers got involved and questioned their sanity and mentioned something called Physics that neither Al nor Albert Ray understood or believed because to them looping a swing was as simple as tying a rock on a string, holding the string in your hand and then swinging the rock until it looped around your finger.
