Luck

In the room there were five cabinets. The space was smaller with only partition to separate it from the other room. The partition only half of the height of the wall, around one point eight metres. Udin saw Elias look angry as he squatting in front one of the cabinet. On his hand was a wooden plaque. He was regretting his action. Elias was waiting for his ten minutes time.

Udin move to last cabinet on the right side of the door. He open the door and inside it he saw a wooden plaque. He take the plaque and nothing happen. He heard a small explosion from the other room and scream from other student. It’s more to shocked than scared. If they were unlucky they will open a cabinet with the trap and need to serve the penalty.
