#2: Chalkboard erasers
For adults, chalkboard erasers were just cleaning tools, but for children, they were a source of mischief. Kids would sneakily toss them across the room, hoping to hit a friend without getting caught. These small, fluffy rectangles were filled with memories of chalk dust and laughter. Sometimes, a well-timed toss could disrupt an entire class, leading to giggles and whispers.
