ple t ▁of ▁water ▁it ▁would ▁form ▁a ▁cone ▁shape ▁and ▁small ▁dro ple ts ▁would ▁be ▁e ject ed ▁from ▁the ▁tip ▁of ▁the ▁cone : ▁this ▁is ▁the ▁first ▁recorded ▁observation ▁of ▁electro sp ray ing . ▁ ▁In ▁ 1 8 8 7 ▁C . ▁V . ▁Boys ▁described ▁“ the ▁old , ▁but ▁little ▁known ▁experiment ▁of ▁elect rical ▁spin ning ”. ▁Boys ’ ▁appar atus ▁consisted ▁of ▁“ a ▁small ▁d ish , ▁ins ulated ▁and ▁connected ▁with ▁an ▁elect rical ▁machine ”. ▁He ▁found ▁that ▁as ▁his ▁stock ▁liquid ▁reached ▁the ▁edge ▁of ▁the ▁d ish , ▁that ▁he ▁could ▁draw ▁fib ers ▁from ▁a ▁number ▁of ▁materials ▁including ▁sh ella c , ▁be es w ax , ▁se aling - w ax , ▁gut ta - per cha ▁and ▁coll od ion . ▁ ▁The ▁process ▁of ▁electro sp in ning ▁was ▁pat ented ▁by ▁J . F . ▁Co ole y ▁in ▁May ▁ 1 9 0 0 ▁and ▁February ▁ 1 9 0 2 ▁and ▁by ▁W . J . ▁Mort on ▁in ▁July ▁ 1 9 0 2 . ▁ ▁In ▁ 1 9 1 4 ▁John ▁Z elen y , ▁published ▁work ▁on ▁the ▁behavior ▁of ▁fluid ▁dro ple ts ▁at ▁the ▁end ▁of ▁metal ▁cap ill aries . ▁ ▁His ▁effort ▁began ▁the ▁attempt ▁to ▁mathemat ically ▁model ▁the ▁behavior ▁of ▁flu ids ▁under ▁electro static ▁forces . ▁▁ ▁Further ▁develop ments ▁toward ▁commercial ization ▁were ▁made ▁by ▁Anton ▁Form h
