This photograph demonstrates surface tension via bubbles. Bubbles are where pressure of the gas inside the bubbles is equal to the pressure from the solution outside the bubbles. A chemical reaction between acetic acid and sodium bicarbonate, vinegar and baking soda respectively, formed the bubbles. A Canon EOS M50 Mark II with a 15-45 mm lens captured this photograph.

Hello Hannah!
I love this! I think his image is going to look great on the big screen at Fiske! The dark shadow in the background really makes you wonder what’s going on. Great job!
Very interesting chemistry. These bubbles and liquids create a hazy feeling. A strange thought: The hazy feeling reminds me of the Japanese Tokusatsu Ultraman, and the mysterious dashed line in the bottom right of the figure could be a light ray emitted by a Ultraman!
I like the clarity of the bubbles in this image, they are very defined against the background.
Hannah! I think this is a great photo taken at a cool angle; it almost feels as if the bubbles are popping out of the page. Love the simplicity of the set up yet the image yields a result that can be interpreted uniquely to each viewer.
Hi Hannah
I like how one can clearly see the bubble, the outline and depth are visible. I also liked the use of orange color and the black shape which helps in capturing the image.
Great work!
Even though this is an overhead shot, there is still a great 3D effect from the small, slightly out of focus bubbles in the background. Did you play around with the ratio of baking soda to vinegar when trying to capture the bubbles?
I didn’t play around with the ratio too much because when I did the effect wasn’t that dramatic. However, I did play around with the distribution of the baking soda in the container as well as the pour speed when adding the vinegar. I found the best results for pictures was to evenly distribute the baking soda across the entire bottom of the container and slowly pour in the vinegar.
I like the distribution of the size of the bubbles and the color.
