4 images compressed into a gif format.

This photo resulted from the use of equal parts cornstarch and water to create a non-Newtonian, shear thickening fluid. This solution was put on top of a speaker while a 25 Hz square wave was being played. Below are two still images of the system.

Taken on a Canon EOS 50D with camera settings: ISO-500, f/7.1, 1/2000 shutter speed, and a 30 mm focal length.

    This was a very creative experiment and the fluid physics here are really interesting. I wish the focus was slightly better to see more details though!

    I would love to know what this looks like in real time, especially with that low of a frequency playing through the speaker.

    Very cool flows captured in this image! It would be very interesting to find out the actual state of the oobleck during compression and tension phases.

    I think that putting the camera at a perpendicular angle to the fluid would give a better view of the patterns. But I like the gif format to see the flow movement in the liquid

    I really like your experiment. Very artistically captured and I like the structure of the patterns that you captured.

    I like the GIF format instead of an image or video.

    This is such a cool visualization of the fluid and sound wave interaction.

    Interesting experiment, showing how sound affects the fluid.
