Do your fingers leave fingerprints on the following...?

all fingers leave minute traces of oil form body / skin secretion.

not all surfaces enable this oil to adhere and others will not let us 'see' the small amount that does. a flat surface can be best.

eg skin . =No ( it does leave minute traces but these are possible to identify from the other skins oils unless it is very different such as leather)

rocks , yes and no depending on the surface of the rock eg smooth marble=yes, rough form nothing worth trying to see to none.

bricks as above.

granite - if polished eg kitchen worktop = very easy .other types and rough vary form difficult yo none.

ice technically yes but most often the skin 'oils' wil not adhere so in effect =no.

I leave fingerprints on any thing I touch hun..
