Mayonnaise is a staple of almost every household, yet the reason why it's so thick and viscous is a long-standing unsolved problem in physical chemistry: why does adding egg yolk to a runny mixture of oil and water increase ...
A novel approach to studying the viscosity of water has revealed new insights about the behavior of water molecules and may open pathways for liquid-based electronics.
