The handheld explosives detector
Another one of those all-too-appropriate gadgets for these all-too-interesting times we live in, you can now pick up
a handheld explosives detector to go along with that baseball
cap that turns into a gas mask. The EVD-3000 can detect traces of C-4, TNT, dynamite, PETN, Semtex, EGDN, DMNB,
RDX, and nitroglycerine in the air, providing results in just seconds.

No, it will not detect most of those chemicals in the air. For many of those chemicals you have to do a wipe with a cloth and then insert. Trust me, I've tried it. And, the company will even tell you that if you ask them. The difference between detection by sniffing and wiping is actually a bigger deal than one might think....
If you go to the site, you'll find it's only $0.00! Shipping adds $0.00 to it, for a grand total of $0.00. I almost decided to order one based on that alone. (Unfortunately, the fine print says to "contact them for pricing information").
