i dont really like the simple describers...kinda tell me they're being lazy.Here I go sensei!
I hold out my hand and begin to focus my chakra into my palm. I think back to my previous lessons and how I manipulated my chakra in the water balloon and tennis ball. I then manipulate my chakra in the same ways I did in those and it starts to take the form of a rotating and spinning ball of chakra in my hand.
