Weissenberg effects are seen when a non-newtonian fluid is put into torsional shear making the fluid climb up whatever is applying the shear. Here the non-newtonian fluid is ‘slime’ made from Borax and Elmer’s Glue.

Love the idea of using a non-newtonian fluid. The light and dark sides on the fluid look great and the photo is very well focused.
I like the flow that you picked to display. The lighting is really nice as well, good technique.
1. The composition and opposing circular lines throughout the image are extremely effective to draw the eye’s focus on the fluid phenomena.
2. The flow is clearly illustrated.
3. The photographic technique and depth of field is nicely done.
Great focus highlights the unique flow occurring. The use of a non-Newtonian fluid and trying to visualize the flow spiraling up the rod. The photo does remind me of a long lollipop seen at candy stores.
– Great photo I can really see the texture in the photo.
– It reminds me of making cotton candy.
– Would be interesting to add a color or dye effect to it.
Great use of lighting! I love the shadows produced with the light coming from the side. What would happen if the black value was set to be the rod visible at the top so the rod was not visible? That might be cool.
Very creative idea to use a Non-Newtonian fluid and make it climb a rod, creating the swirling tower. I like the lighting of the image and the way that the black rod disappears into the dark background. Great image!
Nice image and cool fluid dynamic effect! The spirals in the non-Newtonian fluid being drawn up the shaft really give the image the sense of motion. The focus is right where it needs to be. You will have some interesting physics to discuss in your write up.
Great idea! It reminds me of lollipops at Disneyland. A little bit of detail is lost in the light (but that could just be a resolution thing). The sharp focus is really impressive.
The focus that you have is what makes the image. It’s almost like the ferrofluid display in the lobby of the engineering center. Great job being creative and using a non-Newtonian fluid.
I appreciate the sharp focus that you achieved. I am very impressed with your lighting as well. Really betters the photo. I may have tried to eliminate the bowl from the photo and just had the contrast with the fluid and the black background.
Art: The color contrast between the fluid and the background is very nice and the lighting is really well done.
Flow: The flow is understandable and easily recognized.
Photographic technique: The focus on the fluid is sharp and well captured as well as the use of depth of field eliminates the distraction of the background.
Very interesting physical effects. Never been aware of it before. Focus is really good. Lighting is really cool. Focus is excellent.
This photo is very well focused. The display of the spinning motion in the still photograph is awesome. It shows the whites and the blacks with not to much light.
1. I love this image ! colors are very pretty
2. the spiral shape is fascinating
3. the shadows and lighting is excellent.
Nice capture of the intricate details of the flow as it is being sucked up the rod. Nice work on a build it yourself image. Looks like a melting soft serve cone to me.
-The bright white color of the fluid and shadows on the fluid looks really cool
-Very interesting effect caused by the non-newtonian fluid
-Great lighting and very nice black background
Nice contrast from the background. Excellently focused image, the flow is very crisp. Possibly in the future consider trying to get the bowl out of the image, as it distracts away from the focus in the center.
Nice use of lighting. I like how one side is bright and the other is in a shadow. Interesting flow shown. Good details.
Art: The color is very vibrant.
Flow: The non-newtonian fluid makes a very surprising geometry.
Photography: Great lighting in the background.
Interesting display of physics. The image has great contrast with the black rod and dark background. The fluid flow can be easily seen and provides an aesthetic appearance.
Art: It’s like the fluid is forming a tower by itself.
Flow: Cool to see a non-Newtonian fluid being use.
Photography: Good focus on the rod.
