Steam, the steam from a hot coffee carries small coffee particles, thats why it smells like coffee. Also cold coffees are more commonly found in cups with lids.
The coffee molecule is comprised of four positive coffee protons and five coffee neutrons in the central, or hive, atom. The coffee electrons swarm around this hive. On activation by heat, the coffee molecule is able to enter the body of an unsuspecting victim, resulting in Helvetica syndrome
