"Whatcha doing?!?"
Kai paused in the doorframe of the ninja's shared bedroom. He was dressed in red pajamas, and his hair, usually moulded into perfect spikes, was damp and unkempt after the shower he'd just taken.
Jay was hanging upside down from his bunk bed, arms outstretched towards the floor. He craned his neck to be able to look at Kai, who closed the door behind himself.
"I, uhm ..."
Jay let his head hang again and looked at the ground.
"You know, natural lightning always travels downward."
To prove his point, he directed a small bolt to a spot directly in front of Kai, making the latter jump.
"Hey!"
"Know what I mean? Well, I wondered if I could make the spark come back to my fingers again."
He screwed his face up in concentration and stared at the ground as if trying to hypnotize the floor boards. Sure enough, after a few seconds, a crackling, light blue channel of electricity formed between the floor and Jay's fingers. Sparks crept up, danced over his hands and traveled upward along his arms.
"Pretty cool, isn't it?" Jay stated, satisfaction in his voice.
Kai chuckled, rather unimpressed.
"You're the Master of Lightning. I'd expect you to be able to influence the direction your element takes. Besides, it wasn't really necessary to hang upside down for this. You could've pointed your finger at the ground anytime during training."
Jay pouted. "But I was already in bed when I thought of it. And it's fun."
The lightning traveling up his body became stronger, and the glow around him bathed the entire bedroom in an eerie, blue light.
Kai snorted with laughter. "You look like an electric bat."
Jay stuck out his tongue at him. "Better than a wet firecracker."
Kai ran his hand through his hair, automatically attempting to fix his look even though he had just rinsed out the last traces of gel. "Don't you dare insulting my hairstyle."
Jay cackled, but then he frowned when an idea entered his mind. "Kai, what happens to your element when you're upside down?"
The Master of Fire shrugged. "Dunno. Nothing special, I guess. I could probably set my feet ablaze, if that's what you mean."
Jay grinned and gave him a pleading look. "Oh yeah. Show me!"
Kai rolled his eyes at the silly idea of his team mate, but obediently sat down and rolled back into a perfect shoulder stand. "Here you go."
A flame appeared on the soles of his bare feet; he wiggled his toes a little, and after a few seconds, the fire settled into the shape of a neat ball.
"Works just fine. Bit more difficult than with my hands, though."
Jay burst out laughing. "You should see yourself. That's so funny. Now I know why it's called ..."
He was interrupted by the door opening once again.
"Is this a new bedtime ritual of yours?" Zane's calm, but slightly surprised voice asked.
"Would you mind explaining its meaning to me?"
Jay wiped the tears out of his eyes and turned towards the white ninja.
"Yoga poses," he grinned. "Kai gives an outstanding display of a candlestick, and I," he proudly gestured at himself, "the electric bat."
Zane eyed his friends. The Master of Fire, supporting himself on his arms and shoulders while holding his legs bolt upright, still turned the fireball between his toes, and the upside-down figure of the Master of Lighning sizzled with electricity.
"I see," the white ninja replied unfazed. "This makes sense."
He turned towards his bed.
"Please do not forget to extinguish the lights when you have finished training."
The giggles of his friends were nothing compared to the fit of merriment that ensued the next morning, when Zane earnestly asked Sensei Wu why all yoga lessons covered the candlestick pose in great detail, whereas none of them ever mentioned the equally beneficial pose of the electric bat.
