Story about monster

There was a high school senior preparing her experiment for a science fair at her school. The day of the fair, she placed her beaker on a table and walks away. A boy, known as the school bully, carelessly knocks over the beaker and spills it on himself. The beaker contained DNA of a squid and also DNA of the girl. The liquid splashed onto a nearby extension cord,sending shocks through the boy's body. Moments later, the high schooler returns in a hurry, panicking because beaker had disappeared. A shadow formed behind her as she bends down and picks up her now empty beaker. She slowly turns around as a wet thing taps her shoulder. Mixed with terror and amazement, she screams. The high schooler was mesmerized at her horrific creation.
