It was a regular evening, and Katie was fast asleep in her room. The house was still, except for the faint humming of the growth-ray in the corner.

Suddenly, there was a zap, and a light engulfed Katie. The growth-ray had been accidentally activated. Unaware, Katie slept on, her body starting to grow.

As Katie's body expanded, it began to exert a strange magnetic pull. Iron objects in her room started to levitate, drawn towards her.

Her room was a chaos of flying objects, yet Katie remained asleep, oblivious to the spectacle. She was alone, and there was no one to witness the unusual phenomenon.

Eventually, the noise woke Katie. She opened her eyes to a flurry of objects revolving around her. Fear gripped her as she tried to understand what was happening.

She noticed the growth-ray, still buzzing, and realized it was the cause of her predicament. She tried to turn it off, but the iron objects obstructed her path.

Katie, despite her fear, knew she had to act. She remembered her science lessons about magnetic fields and came up with a plan.

She moved slowly, pushing through the orbiting objects, towards the growth-ray. She reached out and switched it off. The buzzing stopped, but the magnetic pull didn't.

She then remembered that a strong magnetic field could neutralize another. She grabbed a strong magnet from her science kit and held it close to her body.

As she did, the pull lessened. The objects fell to the floor, and she felt her body shrink back to its normal size. She was relieved, but exhausted.

By the time her parents returned, Katie had tidied up her room, hiding evidence of the night's events. She greeted them with a tired smile.

They noticed her fatigue and asked if she was okay. 'Just a long day,' she replied, deciding to keep the night's adventure a secret. After all, who would believe her?
