A Chance Encounter with Bubbles

Yesterday my sister, mum and I visited my niece and great nephew. This is my sister in the garden. What do you suppose she is up to?

Although it may appear that she is practising ballet steps she is in fact chasing bubbles.

When my niece got out a giant bubble blower to deflect Theo from a moment of upset I was off to find my camera.

Item no. 2 in the Summer photo hunt is bubbles. I managed to catch a few.

What a lucky catch!

The question now is which one should I use?
