if not:
I pick my hands up like Gaara does to bring up the shurikens...
As I do this I quickly send out my chakra to the sand and fusing it with my chakra. Then I quickly mold out ten fast moving shurikens and raise them into the air in front of me with my chakra. Then I quickly perform a sweeping motion with my hand(for dramatic effect) and I burst my chakra and make the sand shurikens to burst forward very quickly
