The school bell rang, signaling the end to phsyics lesson, and the start to the long awaited recess break. It was boring for Daera, not that she hates it, but she knew it too well. In fact, she love physics.

Walking in the opposite direction to the of the majority students rushing into the cafeteria, she continued munching on the bread while staring at her notebook with a bag of her precious time travelling gadget and tools tucked in between her arms and body.

'What is it that has gone wrong? Could it be the speed or.. no.. hmm' She thought while trying to flip the pages, brainstorming for possible ideas that caused her failure, and munching on the bread, occasionally pausing to push up her thick geeky specs.
It was her 199th try after creating a portable mini time machine, and this very try was the only one step closer. That is, she could only catch a glimpse of whatever that happened 5 minutes ago, and not any longer than that, neither is she able to actually be physically there other than seeing it as a view.
