Aya smirks. She was proud of her work.
As soon as her Senpai stated her next task, she was shocked, her face neutral, she thought of how she would do the hydrogen and oxygen thing, but she remembered what she learned from the books.
"Alright Senpai, here it goes."
Aya closed her eyes and concentrated, kneaded chakra to her chest and manipulated the water to form a globe at the middle of the lake, it was as big as a basketball ball (>.<)
She then combined her chakra to the water's lake and made it flow to the center of the globe made up of water then, as the chakra runs to the water, its current separates the hydrogen and oxygen, creating a mist around Aya and her Senpai. The globe made up of water dissipates slowly as it turns into mist.
Aya inhaled and exhaled slowly, waiting her Senpai's reaction.
