That no one was there so he started to turn everything off. Starting with the Bunsen burners and finishing with his laptop 10 minutes later.
Satisfied that everything was done and dusted he went to turn off the lights to the lab.
As he turned in the doorway he bumped into someone.
"Watch where you're" he started telling the person before he realised that it was the night security guard, shining a flashlight right in his eyes.
"Afternoon Justin, what are you doing in here?" the guard asked.
"I was just packing up my experiment to head home" Justin responded.
"Here I am checking a light left on and here you are"
The guard sighed as he talked into his radio looking at Justin while shaking his head.
“This is Robert Stevenson, the last teacher must have left the light on"
"That was the last time I'm covering for you, I don't care what the teacher says. It looks bad for me to allow you in here at this time"
The 5'10 veteran guard explained sternly.
"But before you leave, just curious as to your experiment" Robert queried.
Justin beamed as he started explaining the formulas.
Starting with the concept to the formulas even to the production.
Robert could only stare wide eyed as he took it all in.
"Uh, so what will happen with the formulas?" he finally asked.
