Kwame and Suki are standing in a room with a helium balloon tied to a string on the floor between them. Kwame is closer to the balloon. If Kwame blows air toward the balloon, will the balloon move towards Suki or away from her, and why?

Make your response very short.
The balloon will move towards Suki. When Kwame blows air towards the balloon, he creates an area of higher air pressure between himself and the balloon. The helium balloon, which is less dense than the surrounding air, is pushed away from the area of higher pressure toward the area of lower pressure, which in this scenario is towards Suki.
