Phosphorus

"John. John wake up!"
John Watson moaned into his pillow and swatted at the source of his irritation.
"Ow! Okay, okay I get it. You don't want to wake up. But you'll be cross with me if you find out that you missed this in the morning."
John wrapped himself up in his duvet, looking as if he would never emerge.
"OH please John. Stop being such a drama queen."
He opened a bleary eye and glared at Sherlock.
"That's the spirit!" Sherlock said encouragingly.
He grabbed the grumpy Docter's wrist and tried to pry him out of bed. Instead, he succeeded in toppling both himself, and a cocooned John onto the floor. They lay there face to face for a moment, shocked. John pushed himself away from Sherlock, his face red.
"Don't ever," He said threateningly. "Do that again. Or I swear I will go all army on you."
Sherlock got to his feet grinning. "Well it got you out of bed didn't it?"
John mumbled angrily as he disentangled himself from his covers. He glanced at the clock.
"Sherlock Holmes. If you woke me up at bloody 3 in the morning, just so I can answer your phone again..."
"Oh no, it's nothing like that. Although I'm pretty sure my left ear will never be the same again."
John rolled his eyes.
"This time, an experiment has gone rather brilliantly wrong. I thought you might like to see it. I'm fairly certain it isn't poisonous." Sherlock ended thoughtfully.
"Do you EVER sleep..." John grumbled as he followed Sherlock out and down the stairs.
He almost ran into Sherlock as he entered the kitchen. His mouth fell open. All around him were small glowing lights, slightly illuminating the dark kitchen. John glanced up at Sherlock, whose own eyes were filled with a child-like wonder.
"What in the world did you do?"
"Simple John. I was heating a condensed rock of white phosphorus over a bunsen burner... and it combusted. It should wash out quite easily."
John frowned. "But were you wearing protective gear?..."
John trailed off as he saw Sherlock's bloody forearms. He sighed and went to retrieve his first aid kit.
"It's all in the name of science John!" Sherlock called after him.
