Aerokinesis

Aerokinesis is the ability to manipulate the flow of wind and air. This may involve making the wind blow harder, softer or summon strong gusts of wind.

In the film
This is presumed to be Nancy's element since she called the eastern corner by the powers of air and invention, however, in the DVD commentary to the film it is said that this is Bonnie's element.

Nancy, Rochelle and Bonnie use aerokinesis to blow open the balcony doors in Sarah's bedroom, though this possibly occurred only in a nightmare. Nancy uses aerokinesis to blow Chris out of a window, killing him. At the end of the film, Sarah uses aerokinesis to frighten Bonnie and Rochelle.
