The Acro Explosives Testers are a set of disposable pen-size devices capable of detecting mere micrograms of most common explosives--including peroxide-based explosives, which are typically hard to detect and can be made from household ingredients. The bottom of the cap is touched to a suspicious object or person and then screwed back onto the pen. Plungers at the other end are then depressed in sequence to release reagents. An enzymatic reaction produces a color change if an explosive is present.
