A method for developing latent fingerprints includes placing an apparatus in an area having one or more objects. The apparatus has a breakable capsule containing a cyanoacrylate monomer disposed within an internal chamber of a housing containing a cyanoacrylate catalyst and being adapted for emitting vapors. The housing is impregnated with the cyanoacrylate catalyst or has a layer of cyanoacrylate catalyst on a portion of its interior surface. The apparatus optionally has a breakable capsule breaking mechanism for assisting a user in breaking the breakable capsule within the housing. The user breaks the breakable capsule, causing the cyanoacrylate monomer spilling from the breakable capsule to react with the cyanoacrylate catalyst contained in the housing to create vapor fumes. The vapor fumes contact an object being tested to reveal any latent fingerprints on the object.

What is claimed is: 1. A method for developing latent fingerprints on one or more objects, comprising the steps of: (a) placing an apparatus in a target area having one or more objects, said apparatus having a breakable capsule containing a cyanoacrylate monomer disposed within an internal chamber
What is claimed is: 1. A method for developing latent fingerprints on one or more objects, comprising the steps of: (a) placing an apparatus in a target area having one or more objects, said apparatus having a breakable capsule containing a cyanoacrylate monomer disposed within an internal chamber of a housing containing a cyanoacrylate catalyst, said housing being adapted for receiving said breakable capsule and having a means for emitting vapors; (b) breaking said breakable capsule contained within said housing; (c) generating vapors from said cyanoacrylate monomer reacting with said cyanoacrylate catalyst; and (d) developing latent fingerprints on the one or more objects when said vapors contact the objects. 2. The method of claim 1 wherein the target area is selected from a group consisting of a container, box, room, interior of a vehicle, and an open space. 3. The method of claim 1, wherein said step (b) comprises the steps of: (b)(i) engaging a capsule breaking mechanism with said breakable capsule; and (h)(ii) applying pressure to said capsule breaking mechanism to break said breakable capsule. 4. The method of claim 1, wherein said apparatus is contained within a sealed wrapper and further comprising the step of: (e) opening said sealed wrapper prior to said step (a). 5. The method of claim 1, wherein said housing is made of a material impregnated with said cyanoacrylate catalyst. 6. The method of claim 1, wherein said housing further comprising a layer containing said cyanoacrylate catalyst, said layer covering a portion of an interior surface of said housing. 7. The method of claim 6, wherein said layer is selected from the group consisting of a direct application of said cyanoacrylate catalyst to said portion of said interior surface of said housing, and a liner within said internal chamber of said housing. 8. The method of claim 1, wherein said breakable capsule is made of a material selected from the group consisting of glass, plastic, ceramic, composite, and resin coated paper. 9. The method of claim 1, wherein said housing is made of a material selected from the group consisting of paper, fibrous textile, cellulosic fiber, plastic, resin, metal, and composite. 10. The method of claim 1, wherein said means for emitting vapors is selected from the group consisting of said housing having perforations, pores, slots, and one or more open ends. 11. The method of claim 1, wherein said step (b) is performed by a capsule breaking mechanism selected from the group consisting of: a mechanism having a top half and a bottom half pivotally connected, a C-shaped mechanism, a head with a shaft wherein a distal end of said shaft is adapted to engage an exterior surface of said breakable capsule, and said housing incorporating a flange extending into said internal cavity. 12. The method of claim 1, wherein said housing further comprises a resealable side and a means for opening and closing said resealable side. 13. The method of claim 1, wherein said apparatus further comprises a second breakable capsule containing a second catalyst, and further comprising the step of: (e) breaking said second breakable capsule. 14. The method of claim 13, wherein said second catalyst is a sublimation dye. 15. The method of claim 1, wherein said housing further comprises a sublimation dye. 16. The method of claim 1, wherein said housing has a shape selected from a group consisting of a square, rectangular, and circular.
