In summary, the conversation discusses a question about the effects of blowing air between two paper cups hung 10 cm apart. The question is clarified to be about the cups being hung like wind chimes, and the concept of the Venturi effect is mentioned as the point of the experiment. The forum is also mentioned as being the wrong place to ask questions.

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.
 

1. How do paper cup telephones work?

Paper cup telephones work by using sound waves to transmit the sound of a person's voice from one cup to the other. When a person speaks into one cup, the sound waves create vibrations that travel through the string or wire connecting the two cups. These vibrations are then picked up by the other cup, which converts them back into sound waves that can be heard by the person on the other end.

2. What materials are needed to make a paper cup telephone?

To make a paper cup telephone, you will need two paper cups, a long piece of string or wire, and a sharp object like a pencil or pen to puncture holes in the bottom of the cups. You may also need tape or glue to secure the string or wire to the cups.

3. How far can paper cup telephones transmit sound?

The distance that a paper cup telephone can transmit sound depends on several factors, such as the material and thickness of the string or wire, the quality of the cups, and the loudness of the speakers' voices. Generally, paper cup telephones can transmit sound up to 100 feet, but this may vary.

4. Can paper cup telephones be used to communicate over long distances?

No, paper cup telephones are not an effective means of long-distance communication. They are limited by the strength of the string or wire connecting the cups and the quality of the cups themselves. They also do not work well in noisy environments or over large distances.

5. How can paper cup telephones be improved?

There are several ways to improve the effectiveness of paper cup telephones. Using a thicker or more durable string or wire can help transmit sound over longer distances. Using high-quality cups with a cone shape can also improve sound quality. Additionally, using a string or wire that is tightly stretched can help reduce noise and improve sound clarity.
