Episode notes
Purple Shampoo Mechanism
- Purple shampoo doesn't absorb yellow light; it reflects purple light.
- This purple reflection neutralizes yellow tones in hair, creating an ashy or white appearance.
Sugar as Solvent?
- A listener, Julie, and her colleagues discussed if sugar could be a solvent for water.
- They debated whether solids could dissolve liquids, citing dental fillings (mercury in powder) as an example.
Water in Sugar
- Melissa doubts sugar can be a solvent for water because sugar changes when wet.
- Water doesn't disperse within sugar but stays localized, suggesting sugar can't fully surround water molecules.
