Naledi and Takumi are standing on opposite ends of a room with a balloon suspended midway between them at eye level. The balloon is filled with helium. Naledi starts blowing air towards the balloon from her end of the room. What happens to the balloon, and what does Takumi see from his perspective?

Make your response very short.
The balloon filled with helium will move away from Naledi towards Takumi as Naledi blows air towards it. Since helium is lighter than air, the balloon rises and stays suspended in the air, but if pushed by a force such as the air Naledi blows, it will move away from the source of that force. Takumi will see the balloon coming towards him as the air from Naledi's breath pushes the balloon in his direction.
