Add a touch of realism to your forensic science class and turn your students into crime scene investigators!
The Bluestar forensic bloodstain reagent system is based on luminol. It consists of two reagents in tablet form that are dissolved together in water and sprayed lightly onto a surface. If the spray encounters any blood residues, a blue luminescence occurs due to a reaction between the reagent solution and haem, a component of haemoglobin. In dim light conditions, the blue luminescence is easily seen, even on very dilute blood residues..

Demonstrate real forensic techniques
Explain this form of luminescence in terms of a release of light energy.
Please note that Luminol will only work on real blood.
