This instructable describes the process of building a chamber for superglue fuming. Superglue fuming is a method employed by criminal investigators in order to take and preserve fingerprints, before sending them to the lab. By heating superglue, the fumes react with the oils left by the fingers on the suspect object, revealing latent fingerprints and preserving them. Making a fuming chamber is actually pretty simple and relatively safe, if you follow a few safety precautions. I will show you how to build a quick makeshift chamber that nonetheless works very well.
