The Home Scientist 006 - Forensic Fingerprinting I: Iodine Fuming

[@MATT-AT]

You have a Morgan Freeman tone in this video, I can't be the only one to hear this, was extremely calming whilst I was watching this hearing your instructions as it were, neat video aswell I would've loved it if our science at school did some more practical stuff when I was there, they just left most of the heavy lifting to computers, got to dissect some stuff though, You've a new sub :)

Cyanoacrylate fuming is a possibility ('Super Glue') - or the application of photoluminescent nanocomposites and a UV source. The likelihood of getting any usable material depends upon how porous the rock and how recently it was touched. Frankly, you're probably not going to be able to get anything. The pores in the material disrupt the the print - sort of like painting over a rough surface.

Hi Robert. Writing for a friend. Why does the solution taste so bad when swallowed in large quantities? Also, it seems to stain the eyeball. Please respond. Thank you.

Can you tell me please is thermal paper also needed to clean from blanket or hot blanket or water?

[@yahoorif]

could it be fatal if I accidentally inhale the iodine vapour?

[@blueduderanch]

awesome, thanks for clearing that up.

[@Sakura123STARS]

Is it okay if you use the liquid iodine instead of the crystals?

[@blueduderanch]

ninhydrin is carcinogenic isnt it, and i comes up with a purple colour. we use it to visualise amino acids.
