Here is a theft deterrent idea...
What if you could spray your valuables with an invisible DNA-like identifier, unique to you. What if this brilliant agua could also be used to link a suspect to the scene of the crime. What if this water could only be seen using ultra-violet light. You would probably say, "That's smart water." (knock, knock) Excuse me. (whisper, whisper)
Right, well then... apparently this has already been done.
