Claim:
1. An aerosol creation system, comprising: a first pair of counter-rotating rollers; a first nip defined between the first pair of counter-rotating rollers, the first nip having an upstream side and a downstream side; a second pair of counter-rotating rollers positioned adjacent to the first pair of counter-rotating rollers; a second nip defined between the second pair of counter-rotating rollers, the second nip having an upstream side and a downstream side; a fluid source that coats at least one of the rollers in the first pair of counter-rotating rollers and at least one of the rollers in the second pair of counter-rotating rollers; a driving element structured to drive at least one of the rollers in the first pair of counter-rotating rollers and at least one of the rollers in the second pair of counter-rotating rollers to cause fluid to be drawn through the upstream side of the first nip to the downstream side of the first nip and through the upstream side of the second nip to the downstream side of the second nip, wherein a first fluid filament is stretched between diverging surfaces of the first pair of counter-rotating rollers on the downstream side of the first nip until the first fluid filament breaks into a plurality of first droplets, and wherein a second fluid filament is stretched between diverging surfaces of the second pair of counter-rotating rollers on the downstream side of the second nip until the second fluid filament breaks into a plurality of second droplets.
