Fast, reliable, well-resolved latent fingerprints canbe planted by applying a thin coating of a 50:50 mixture of handlotion and food-grade protein powder. Fingerprints can be revealedwith iodine fuming or ninhydrin staining. This low-cost alternativeto commercial latent print pads can be used in a variety ofclassroom or public settings where the chemistry of fingerprintstaining is to be discussed. The current work was completed in thecontext of a university, nonmajors’ chemistry laboratory but can bebroadly applicable for other university classes, high school classes,or public demonstrations.
