Hello. I need some help of understanding what forces are causing one of the cups to fly out of the other one when you blow at it. This video describes the experiment.

1. What is the physical force that causes the cup to fly out?
The physical force most likely causing the cup to fly out is air pressure. When a person blows on the rim of the cup, they create a region of high air pressure inside the cup, which pushes against the inside of the cup and can cause it to fly out.
2. Can the shape or material of the cup affect its ability to fly out?
Yes, the shape and material of the cup can affect its ability to fly out. A taller and narrower cup may have a stronger reaction to the air pressure, causing it to fly out further. Additionally, a lightweight cup made of thin plastic may be more easily pushed by the air pressure compared to a heavy ceramic cup.
3. Is there a specific angle at which the cup is more likely to fly out?
The angle at which the cup is held may impact its ability to fly out. If the cup is held at a slight angle towards the direction of the person blowing, it may have a stronger reaction to the air pressure and fly out further.
4. How does the force of the person blowing on the cup impact its flight?
The force of the person blowing on the cup can impact its flight by creating a stronger or weaker air pressure inside the cup. The stronger the force, the higher the air pressure and the further the cup may fly out.
5. Is there a way to prevent the cup from flying out?
Yes, the cup can be prevented from flying out by either decreasing the force of the person blowing on it or by increasing the weight of the cup. This can be done by using a heavier cup or by filling the cup with a liquid to add weight.
