Blowing between two paper cups hung 10 cm apart demonstrates the Venturi effect, where a change in air pressure occurs. The discussion clarifies that the cups are likely hung like a traditional telephone rather than wind chimes. The focus is on the interaction between the cups when air is blown between them. The positioning of the strings is deemed less relevant to the experiment's outcome. Ultimately, the experiment illustrates principles of fluid dynamics and pressure changes.

OKay this question is so vague. I need opinions on what it could possibly mean.

What happens when a person blows between two paper cups that are hung by strings 10 cm apart?

Now i am trying to imagine how this would look. Is the string going through both cups like one of those little kid paper cup telephones?

OR

Are the cups tied to separate pieces of strings like windchimes and have a distance of 10 cm between them?

I think it is the telephone version

The question would only make sense if they are being hung like wind chimes. Think about the change in pressure between the cups when you blow between them.

Also, this is the wrong forum to ask questions.
 
It doesn't matter what the strings do at the top.

Two cups, hung 10 cm apart. Period. (i.e. your second option)

The point of the experiment is, when you blow air in the gap between the cups, what happens to the cups?
 
This is a demonstration of the Venturi effect.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
