DNA Spray?


DNA spray? What's that? 

S started noticing these signs in shop windows all over town and was really curious about them. After a little bit of research we learned they're an anti-robbery system. Above the door is an orange box, that can be triggered by an employee if there is a robbery. When triggered the box  sprays a super fine mist on anyone passing by. The tiny particles are detectable by UV light and contain a unique DNA sequence - specific to that location  - tying the offender to the scene of the crime.
