The device

It was 9pm on a sunday. sarah was on her phone taking selfies when it ran out of battery. Her stupid sister was using her phone charger to charge some stupid experiment she was making.

Sarah went into her sister's room to grab her charger. She seen it on a desk and went to grab it. As she was taking it though she noticed the device.

It was shaped like a square with a red button in the centre. She picked it up to see what it would do. Her sister walked in and started shouting at sarah to drop it.

Sarah pointed it at her sister and pressed the button.
