How Tears Dry

Tears are 98% water, with the remaining 2% containing salts, glucose, proteins, and lipids. As they evaporate, water disappears first, leaving behind tiny crystalline traces.

Interestingly, emotional tears contain more proteins than reflex tears (like from cutting onions), affecting how they dry. A little chemistry in every tear! 🔬💧
