Experiment with CD

  1. Jul 27, 2014 #1
    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 physic 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 blown
