How does Vanishing Rasengan work?


Vanishing Rasengan is a miniature Rasengan which was originally developed by
Boruto as seen in Boruto: Naruto the Movie. In that movie, when Boruto was
trying to learn Rasengan in front of Sasuke, it was observed that his Rasengan
usually vanishes into the air but the effect of Rasengan is still there.

How was Boruto able to make the Rasengan vanish? How does Vanishing Rasengan
work?




As [wiki](http://naruto.wikia.com/wiki/Vanishing_Rasengan) said, Boruto create
a miniature of Rasengan then he inject the Rasengan with Wind release nature,
so the it can be thrown.

About your question how Boruto was **able to vanish** the Rasengan, I think
because it's so small, slowly vanishing while thrown but still hits the target
because his Wind Release nature. But it's only my opinion of course.
