CSI technicians use powder or chemical solutions to make fingerprints visible on surfaces. They carefully lift the prints using tape or specialized tools without smudging them. The lifted prints are then analyzed and compared to known prints in databases to identify potential suspects.
Forensic investigators use various techniques to identify and lift fingerprints from a crime scene. This typically involves dusting for prints with powders or chemicals, then lifting them with tape or adhesive sheets for analysis. Advanced methods such as using lasers or alternate light sources can also reveal hidden prints on different surfaces.
Permanent hand prints in a mirror could be caused by oils and dirt left on the surface from repeated touching. Regular cleaning with a glass cleaner should help remove the marks.
The negatively charged rod induces a positive charge at the side of the can closest to it, attracting negative charges to the opposite side. When you touch the opposite side with your finger, electrons flow from your finger to neutralize the positive charge. If you remove your finger before removing the rod, the positive charge induced by the rod will redistribute, making the can net-neutral again.
Fingerprints are detected using techniques such as powder dusting, chemical solutions, or lasers. These methods help to reveal the unique ridge patterns present on the skin's surface, which are then captured and analyzed for identification purposes.
