Dry ice submerged in dyed oobleck (corn starch and water suspension) creates foggy geysers as the bubble opens a slit.

Dry ice beneath dyed oobleck (corn starch and water suspension) creates foggy bubbles that splatter dye as they pop.

Blue milk and then yellow milk were injected into clear detergent in a Hele Shaw cell to create the Saffman Taylor fingering instability.

Blue milk and then red water were injected into clear detergent in a Hele Shaw cell to create the Saffman Taylor fingering instability.

The Saffman-Taylor instability in a Hele Shaw cell resulted from yellow dyed milk injected into a blue detergent, previously injected into clear liquid detergent.

A ‘bathtub drain vortex’ forms when two water bottles are connected vertically. The surface of the vortex is visualized by red lamp oil.

A horizontal soap bubble film drains towards its center, while nonuniformities from undissolved sugar crystals create colored patterns as the film thickness varies.
