Once upon a time, there was a leader of a pyrotechnics team who loved putting on spectacular shows with gunpowder. Before each show, the leader and his team worked hard to mix the right chemicals to create the perfect lift charge for their mortars.
On show night, the crowd watched in awe as the shells were launched into the sky and exploded with a loud salute. The bursting charges created bright colors and amazing patterns in the dark sky.
But one time, the leader realized he had made a mistake with the time fuse on one of the shells. He quickly raced to fix it before the show continued, saving the audience from danger. From that day on, he made sure to double check all of his work to ensure a safe and spectacular show every time.
