How does it work?
Unfortunately, this section is only available in the e-book version of the project.
The ridges that are on the outer layer of your friend’s skin are blackened by rubbing it against the pencil mark. By pressing the finger on the sticky tape, the ridges come in contact with the glue from the sticky tape and are rubbed off leaving a fingerprint impression. The print is preserved by sticking it on the paper.
