Fingerprint Forensics

Step into the shoes of a crime scene investigator with this hands-on forensic experiment! Using the surprising power of iodine vapor, citric acid, and hydrogen peroxide, you'll reveal secret fingerprints just like in the movies—no black powder needed!

Watch as invisible prints magically appear and change color through a chain of chemical reactions. The iodine clings to fingerprint oils, while the citric acid and peroxide team up in a bubbly color-changing twist that feels more like wizardry than science!
