Frozen Bubble Escapades – Part I

I first saw a photo of a frozen bubble last year – too late in the season for me to try them. I completely forgot about them until they started appearing in my Facebook feed this year. I had just one day left of a frigid cold front in our area, so I did some quick research online, gathered supplies and spent three glorious hours watching bubbles freeze on my back deck the next morning. Weather-wise it was 12° F / -11° C when I started and warmed up to 20° F / -7° C by the end. Also I felt no discernible wind and none was detected by my weather station.

My Bubble Solution

There are many different recipes for homemade bubble solution to be found online! After watching a kid’s science video that explained why bubbles pop (they evaporate), I decided to use a recipe with glycerin because that significantly slows the evaporation process allowing the bubbles time to freeze. I used the recipe found in this article, but added some sugar because yet another article mentioned that it helps enhance the crystals in the frozen bubbles.

My bubble solution recipe:

1 cup water
2 Tbsp liquid dishwashing soap (I used Dawn)
1 Tbsp glycerin
1 Tbsp sugar

Blowing the Bubbles

A straw* is the easiest way to control both the size and placement of the bubbles. (I also used a piece of clear vinyl tubing which worked the same as a straw and is ultimately less damaging to the environment if added to your photography tools for long-term use rather than being disposed of.) Keep the size of your bubbles between 1 – 1.5 inches (2.5 – 4 cm). I didn’t have much luck with bubbles larger than that – they popped well before they finished freezing. Smaller bubbles don’t seem to evaporate as quickly and they are not as fragile in a slight breeze. Just move in close with your camera to fill the frame with the bubble and no one will know they aren’t very big.

Photographing the Bubbles

The direction of the light makes a huge difference in the way your camera captures the frozen bubble. If you want your frozen bubble to look like clear crystalline, position your camera so that the bubble is back lit as much as possible. You don’t want your camera pointing into the sun, but just outside of the frame of your shot for greatest impact.

Alternatively, if the light is off to the side, the frozen bubble will look more milky/pearly. The following two photos are of the same bubble, but taken (with my cell phone) at different angles to the light.

Another important factor in photographing frozen bubbles is having a dark background behind the bubble. This could be a shaded area (with the bubble in sun) or you can hold a dark backdrop behind it. The beautiful crystal patterns in your bubble won’t show up as well against a light background.

The colder it is, the faster the bubble will freeze. At the coldest temperatures, my bubbles froze within 30 seconds. It was difficult to blow the bubble, return to my camera and nail the focus before the bubble finished freezing, so all of my best shots were of a fully-frozen bubble. However, once the temperature warmed up a bit (above 15° F / -9° C) it took a minute or longer to freeze, which gave me time to compose, focus and capture partially frozen bubbles in addition to the fully frozen ones.

The Effect of Temperature on Crystal Formation

In most of the photos I’ve seen of frozen bubbles, the crystal patterns have what looks like a leafy or feathery structure. But the pattern I got at first looked like a bunch of little hexagons that grew together over the surface of the bubble. In fact, the bubble started freezing before I had even finished blowing it! I wondered if it might have to do with the temperature of the bubble solution. I had left mine in an unheated garage overnight and as soon as I brought it out into the 12 degree temps, it started getting slushy. I.e., it was very cold!

I decided to mix up a new bubble solution so that it would be at room temperature. When I tried that solution 20 minutes later, it was about the same temperature outside (just 2° F warmer). Lo and behold, the crystals formed much slower (50 seconds to freeze the entire bubble) with the warmer bubble solution and the crystals looked much more feathery. (Note that this is just one data point and there may be other factors that affect the shape of the ice crystals such as minerals in the water, exact temperature of the bubble solution, etc.)

Obviously the air temperature made a difference in how long it took for the bubbles to fully freeze, but I was surprised at how big of a difference:

12° F / -11° C with very cold bubble solution: 33 seconds

14° F / -10° C with room temperature bubble solution: 51 seconds

20° F / -7° C with room temperature bubble solution: 4 minutes!

As I mentioned in the Photographing the Bubbles section, the longer it takes to freeze, the more chance you have to compose, focus and take a series of photos. The downside is that the bubble is much more apt to burst before fully freezing – especially if there is a breeze. Your best bet is to keep your bubbles small and sheltered from the wind.

Our frigid temps have unfortunately lifted for the foreseeable future, but I plan to run some more experiments once they return. Stay tuned for Part II of my Frozen Bubble Escapades!

About the Author:

I’m a self-taught photographer and way back when I used to love taking photos, but I allowed a business that I started in 2004 to take over my life and my photographic repertoire was reduced to quick product shots and how-to tutorials. When I joined the PhotoChallenge in December 2015, I was looking to rekindle my creativity and bring some joy back into my photography. I jumped in with both feet and have not looked back. I believe that photography can change the way we see and interact with the world around us. Some people may think that I hide behind the camera, but I feel that I experience the world in a much more intimate way when I am creating a composition in my viewfinder. In those moments distractions disappear, my mind focuses and I am fully present. It is just me and my camera capturing a moment in time that might otherwise go unnoticed. My background is as varied as the photos that I take. I’ve trained and worked as a software engineer, a massage therapist, an English teacher in Vietnam, a photo restoration artist (which is how I learned Photoshop) and for the past twelve years I have run a small software business with my husband where I have been published in numerous books and magazines, appeared on PBS television, created designs for fabric, quilts and machine embroidery and won awards for some of my quilts. It should come as no surprise that I am intensely curious about life and love to learn new things. I am blessed to live in the beautiful state of Colorado, USA in the Rocky Mountain foothills outside of Fort Collins with my husband and cat.

    Thank you for your article on frozen bubbles and how to photograph them. I found it fascinating and interesting. I live on the West Coast above San Francisco and the coldest it gets here in the dead of winter ranges from 28 -34 degrees with exceptions on certain occasions. The only thing that’s cold enough to freeze bubbles around here would be my freezer but I don’’t think the effect would be the same……..probably end up with a solid frozen bubble!

      Thanks for taking the time to comment Henriette. I think you are correct – it’s not cold enough where you are to freeze bubbles. So far this winter, I’ve had mostly similar temperatures, so your freezer idea now had my curiosity piqued. 😉

      You’re very welcome Bill! I can’t wait to see what twists you put on it in your own photos. I can tell from your website that you like experimenting as much as I do. 🙂
