they use this weird powder
If you get ink on your fingertips, from an ink pad or by any other means, you can then print your fingerprints on a piece of paper, just by touching it. Once the fingerprints are printed on the paper, you can then show them to people.
Technically speaking, one cannot "lift" prints from paper like any other solid object, as paper absorbs liquids that it comes into contact with. However, by applying chemicals, such as certain forms of nitrate, will make the fingerprints appear brown, which can then be scanned onto computer or copied or photographed. The real answer to this question also depends on how well the paper absorbs body fluids and the strength of the chemical applied. (for example, thermal paper can be troublesome to take prints from)
In reality when a fingerprint is found at the scene of a crime it can be dusted with chemicals to make it easier to see and then lifted or photographed.

It is processed with chemicals that make it white. Bleach is one thing that is used along with other chemicals.

Paper is a reuseable resource that can be recycled. Trees must be cut down to make paper, and harmful chemicals are used in its manufacture.
The chemical used to make toilet paper from recycled paper is h02 + Co2 --> h04C2 why do you bother about "The chemical used to make toilet paper from recycled paper is h02 + Co2 --> h04C2" oh my god you are weird NERD
u can make it on paper, fingerprints, markers, colored pencils, ect.... u can buy one, make one out of nature things and try to be creative
Photo paper is not recyclable. There are chemicals in the paper which make it impossible to be handled for recycling the same way standard paper must be.
No, you cannot use ethiol to make fingerprints show up. However, you can certainly use ethanol to make fingerprints show up.
The paper mills take pine trees and debark them. Then break them down and use a lot of chemicals and machines to make the paper and board. The chemicals are very dangerous. Green liquor, white liquor, black liquor and lime.
