Click For Summary
The discussion centers on an experiment involving making bubbles using a heated CD. The process relies on applying force through blowing, which is enhanced when the CD is heated, allowing the plastic to melt and deform into a bubble. The molecular physics behind this involves the properties of the plastic as it transitions from solid to liquid and then forms a bubble. Participants compare this to the familiar method of blowing soap bubbles with a loop. Overall, the experiment illustrates the principles of heat and pressure in creating bubbles from a solid material.

Hello, everyone.
I saw this experiment:
A man is doing experiment with part of CD. He is making bubbles on it.
It is really interesting for me, but I really don't know how it works from physics view.

The blow makes some force with pushing on CD and it can push better if the CD is hot, yeah?
But how it can make bubbles? What is happen from view of molecular physic?

Thank you very much.

have you not blown soap bubbles using a loop ?

this is just the same. He just has to heat the plastic hot enough so that it will melt and deform
in this case into a bubble when it is blownDave

Thread 'What is the pressure of trapped air inside this tube?'

As you can see from the picture, i have an uneven U-shaped tube, sealed at the short end. I fill the tube with water and i seal it. So the short side is filled with water and the long side ends up containg water and trapped air. Now the tube is sealed on both sides and i turn it in such a way that the traped air moves at the short side. Are my claims about pressure in senarios A & B correct? What is the pressure for all points in senario C? (My question is basically coming from watching...
