Last time I asked what would have more individualizing power in an ideal world: DNA or fingerprints? They both have solid science behind them, and are known to be unique to every person.... but there’s one exception! The DNA of identical twins is exactly the same. As they come from the same egg, any differences in their DNA would need to occur after conception. While there’s always the possibility of mutations occurring during growth, or as a result of a substance introduced after birth, there’s also the possibility (and probability) that identical twins will have identical DNA, especially since forensic analysis only considers certain sections of the genome. Fingerprints, however, arise as a result of how we move and what we touch during gestation. This means that two twins will have different fingerprints, because no one will move in exactly the same way throughout their pregnancy! So the answer is that, in a world where analysis and evidence recovery is perfect, fingerprints have more power!
In reality though, identical twins aren’t usually an issue and the methods developed for DNA analysis are far more reliable than the methods for fingerprinting.

Tips & Tricks for thermal paper development:
make sure your receipt is thermal paper by scratching it with your nail! If a silver/grey line shows up where you scratched, you’re good to go.
rub your finger on your face or neck to increase the oiliness of the print. This obviously doesn’t mimic crime scene conditions but will help ensure your print shows up.
beware of microwave hotspots which may over develop spots of your receipt! Real forensic ident officers don’t use microwaves, they use other forms of wet or dry heat like steam and heat guns. You can try using your oven or holding your paper over a kettle as well!

Im so happy with this so far. Messiness adds to the beauty. Here is a tiny sneak peak video for you all while I work now on getting the rainy effect in this finger painting. ( oops my screen became blue while typing this)
