Mother Nature Blowing Bubbles

A phenomenon we've seen at the cabin quite frequently when it's raining is bubbles on the surface of the calm water in our natural swimming pool.

S.T. Thoroddsen of the National University of Singapore gave a presentation at the 2001 meeting of the American Physical Society:

The formation of bubbles on puddles is a common sight during heavy rain. Here we investigate the impact dynamics during bubble formation. High-speed video shows how the well-known Worthington crown closes above the crater to form the bubble. The closing bubble forms two jets one going up and the other down into the forming bubble, thus creating a toroidal cavity, which becomes unstable leaving a single bubble.
That's a very scientific explanation for such a natural process.

While all of these bubbles were forming on the calm water behind our cabin, there were absolutely none out front where the wind was rippling the water's surface. I wonder if that was part of his presentation.

Here's a video of the bubbles in action.



Have you ever noticed this trick of Mother Nature? -- Margy

    1. This is the first place I've ever noticed them, and only in the protected spot between the cabin and the rock wall. Out front there is always too much of a breeze on the water to let it happen. - Margy

  5. Amazing! I have seen that before and just thought it was the force that the rain hit the puddle that caused the bubbles to pop up.

  6. Thanks for the scientific explanation Margy - I'd not thought about it before, although this phenomenon often happens when we've had heavy rain and water pools in a section of my patio. This is when my sweet dog Jessie has great fun trying to eat the bubbles!! (She is good value as an entertainer!)

  7. I'm glad to know that when I see bubbles in the puddles it's because it's a natural thing. I thought it was pollution.

  8. Very nice!

    When I'm visiting your blog with Firefox I'm getting intermittently hijacked to gogardenclub.com; my research shows this may be related to the Site Meter widget. It's happening on numerous blogs with that widget...
