Forensic Science Kit
This product ROCKS! I've been a big fan of CSI for ages, and looked foreward to solving the case - there's a lot to read, which I enjoyed - it really makes you think it all through before you proceed to the forensic tests that are included. My personal highlight!
If you are as much into forensic science as I am (or just into it in a normal and healthy way;)), do yourself a favor and try this kit out. You wont regret it!
