So many possibilities, but just five photos allowed for this (and every) month’s theme: liquid! We all need liquid to live. We also need to be liquid (i.e. flush with cash) to pay our bills! 😉 In phonetics, liquid is a consonant produced by allowing the airstream to flow over the sides of the tongue, and able to be prolonged like a vowel (typically l and r ). Who knew? Liquid is also a phase of matter, where particles are free to flow – which means while a liquid has a definite volume, it does not have a definite shape. Have I convinced you yet there’s a lot of scope to be creative with this one?
I aimed to create a good mix of subject matter, and had lots of fun exploring various characteristics of matter in the liquid state, things like density, polarity and refraction. Here are my favourites:
1. Coffee, elixir of life
If you’re a coffee drinker, you know exactly what I mean! If you’re not, there’s no explaining it. 😉
Out for a Saturday morning walk, we spotted two sets of footsteps in the fresh snow. Mr GeoK opted to go with the flow and follow them. End result? We discovered a new-to-us hiking trail in Canmore. For several km, the trail roughly parallels Stewart Creek, climbing upstream, before turning sharply right up a steep screen slope, eventually reaching the summit of the middle peak of Three Sisters. We turned back after 90 minutes, so didn’t even make it to the spot where the creek emerges from an underground karst system. But we did see several waterfalls, of which this was the tallest.
The instructions for this home made “lava lamp” are pretty easy. Fill a container about 3/4 with some kind of cooking oil. Add water to bring the level up to about 7/8. Add a few drops of food colouring. Drop in an Alka-Seltzer tablet and enjoy the show!
I posted a BTS video on my Instagram here.
The oil and water start out in distinct layers (oil on top, water on bottom) because of their relative densities. And what prevents the oil and water from eventually blending together as a result of all that Alka Seltzer-induced action is that they have different polarities, so the oil and water molecules also repel one another.
Water – a liquid by definition – has the abilities to reflect and refract. I posted some water droplet refraction images for the August 2018 PBC and I haven’t tried them since. This is one type of photography that definitely improves with practice. In my option, the guru of water droplet refraction macros is Canadian Don Komarechka. He’s going to be in Calgary next month for a workshop and a Q&A. I’m hoping to make it to at least one of those events.
5. Walking water
In this set up, water appears to defy gravity. But it actually moves because of capillary action. The adhesive forces between the water and the paper towel are stronger than the cohesive forces inside the water. As a result, the water travels up and across the paper towel out of one glass and into another, until the water levels are equalized.
I procrastinated a bit this month, so I didn’t set up the colour-changing, walking water experiment until late morning on October 30th. I let in run for 28 hours, popping downstairs to check on things every few hours during my usual awake time. After 28 hours, the water levels were not fully equalized and the colours were not fully blended in glasses 2 and 4. I am going to leave it set up for one more night, and hope that by morning the result will be closer to what I expected. Regardless, I’ll post a comment with the final result before I clean everything up.
I’m going to break the five photo limit here by showing the end result…
…and a slide show that shows from start to finish (photos taken at random intervals):
That’s it from me! I’m excited to what other photo blogging challenge participants did with this month’s theme. And I’d like to hear from you! What’s the first thing that comes to mind when you think of liquid? Please share by leaving a comment (photos welcome).
Finally, please consider joining the photo blogging challenge! I think of it as a low-stress photo assignment – a regular prompt to hone my camera skills. For each month’s theme, you’re asked to share five photos snapped with your choice of camera. The amount of accompanying text is up to you. The next theme will be posted at a ‘lil Hoohaa in early November.

You always come up with some awesome and creative ways to interpret a theme. The water falls are fantastic, the homemade lava lamp is way too cool, and that color experiment… now that is wild. Learn something new!
As for the coffee thing… don’t drink it, so …
Oh my goodness I thoroughly enjoyed your take on the theme. Each one was a great shot and filled with information, thought provoking and interest. Thank you
Awesome Awesome post! Love these pictures 🙂
The colors in the lighting of the coffee machine are wonderful. And I love the walking colors. So creative. Your entire selection is so creative. I’m going to have to try the lava lamp one.
Such a fabulous, creative post! 👌🔥 The walking water experiment is especially fascinating and I agree about the coffee. Couldn’t do without it!
Wow, you went all the way! Love your scientific approach (have you ever tried the Coke/Mentos
experiment?) as well as the gorgeous nature pictures, especially the droplets. Will the waterfall freeze as it gets colder?
You certainly put a lot of thought into this post. I really enjoyed it. I love the lighting in the first one. I’ve heard about making a lava lamp and I think that would be fun to do with the grands.
Hi, I love the coffee photo and the walking water is so interesting. Thanks so much for sharing your liquid shots. Love seeing them. Sylvia
The walking water was really cool, but I think my favorite of this month is your snow shot.
