This image shows a penny with water carefully placed on top using a dropper. The surface tension and adhesion allow the water to rise above the edges without falling off.

I like how you can almost see the reflection of the penny on the surface of the water and you can really see the limit of the surface tension
I think you did a really great job with the framing and the focus in this photo.
I like how you captured the smooth curvature of the water over the penny due to the surface tension.
I like the simplicity of the photo and the phenomena you chose to visualize. I also like the distance and scale you chose for the subject in your final edit. You may have tried this, but I think a longer exposure at lower ISO might bring out the depth in the image. I also wonder if by showing an exact side profile instead of a partial top view might allow for better viewing of water on the penny instead of the penny colored backdrop. Nice job capturing such a small subject so well.
great demonstration of cohesion and adhesion!
I find it fascinating that pennies hold water so well. I love this demonstration of physical behaviour.
Really interesting image Brian! It’s a very simple yet elegant way to display some interesting fluid mechanics.
This is a nice simple image that keeps the focus on the subject. It is interesting that the water acts as a lens that shows the surface of the penny even though it is almost parallel with the camera.
I enjoy the composition of this photo, the simple white background draws the viewer’s attention only to what you want to focus on in the image.
I think you did a good job sticking to the rule of thirds. The bright reflections on the edge of the penny are also very interesting. Maybe a shinier penny would be curious to see as well!
This image has a nice focus, I really like how we can see the face of the penny reflection. Its an interesting depiction of surface tension as well.
I really like the idea behind this image. The surface tension is very clear in this.
Do you know how many drops it would take for the water to flow over the penny?
I like the simplicity of the the color scheme of the surroundings. It keeps the focus on the penny.
I like the white background and the focus on the adhesion between the penny’s surface and the water.
I like how you can see the image of the surface of the penny, even though the perspective is from the side! Cool optics!
