Surface tension is actually a tension. Watch how the soap film acts like a thin elastic band.

      this is so fascinating! it’s amazing how surface tension works like a thin elastic band. science really does have its cool moments!

    2. Oh, this is a very interesting experiment! It seems to me that this should be done in schools to make it more interesting for children to study physics

      Nice demo. I bet it’s hard to set up the copper wire so it’s coupled tightly enough to the steel pins but can still slide freely on both ends.
