colloids
Fog and milk
Colloids are mixtures where tiny particles of one substance are dispersed throughout another without dissolving or settling out.
Milk, fog, and gelatin are colloids—the particles are larger than molecules but small enough to stay suspended indefinitely.
Colloidal silver refers to silver particles suspended in liquid, marketed as a health supplement.
The adjective is colloidal.
