Liesegang Rings
21 days ago
- The author explores physics phenomena that remain consistent when scaling down dimensions and aims to create complex tabletop experiments.
- Previous experiments include Rayleigh-Bernard convection cells using mica powder and oil, demonstrating non-equilibrium self-organization.
- The author is investigating Liesegang rings, which form geometric patterns in gels and are chemically interesting yet not fully understood.
- Safer versions of Liesegang ring experiments were identified using agar jelly, magnesium chloride, and sodium hydroxide instead of carcinogenic chemicals.
- A first attempt to replicate Liesegang rings failed due to unclear band separation, likely from issues with gel preparation or timing.
- The author shares both successes and failures to promote transparency in independent science.
- Protocols from older papers (e.g., Chopard 1999) are more feasible for home labs due to accessible and less hazardous reagents.
