Are you always curious about what exactly a substance in your posession is? Do you always mix up your anthrax, cocaine and baking soda and need an easy way to determine which is which? Well, say hello to the Thermo Scientific FirstDefender RMX!
This handheld device instantly identifies pretty much anything, be it nerve gas or passed gas. Sure, it's meant to be used by soldiers or mounted to the front of tactical robots, but what's to stop you from getting one for yourself? I mean, besides the price, of course, which is a whopping $32,000. But otherwise, completely reasonable.
