Soap Bubbles

Firstly yesterday's Mystery Macro Challenge. 
Congratulations to greg_lovett and tedwin, you both got it right yesterday.
Please see extra for the solution and thank you all for guessing. It was a great challenge for us all :-)

When washing the dishes I saw soap bubbles formed on the soap bootle pump and kind of liked them and managed to capture them before they were gone.

Have a lovely day.
