Fishing
A fish swam gracefully in the calm, shallow waters of a section of the winding river, its scales glistening in the sunlight that penetrated the crystal clear surface of the water. It moved with elegant grace, gliding smoothly with its school.
Klaus watched the fish carefully, calculating the exact moment to act. His focused eyes followed the animal's every move as it prepared to attack. In an instant, Klaus launched the spear at full speed, slicing through the air, breaking the surface tension of the water, and landing on the fish.
The other members of Klaus' group and some students on the other side of the river kept their eyes on the scene, holding their breath in anticipation. Everyone was waiting for the outcome of the daring action. Some doubted that Klaus would actually catch any fish with such a rudimentary technique. But others didn't say anything until they saw the final result.
