En dernier ressort : les ressorts

To pick coconuts, Tom has developed a clever technique. His mammoth lowers the branches of the coconut trees with a rope, and Tom only has to raise his arms to harvest the fruit! But one day, he accidentally discovers that harvesting can be even more efficient and deliveries faster thanks to springs. By using leaf or spiral springs, where the flexibility of one or more metal leaves stacked on top of each other is used, they have mastered the movement needed to make the work easier at the family plantation.
