Yes! you sure can! Depending on the content of the fingerprint there are a few methods on the market to enhance prints. SPR or Small Particle Reagent can be used when the item is still wet and a print pops up. If you search it you will find that SPR adheres to our fatty acids in the fingerprints we leave. Another method is Physical developer which uses a redox reaction to enhance the print. Kind of like a photographic image.
Oils on skin surface
The "wetting" that happens when an object is immersed in a liquid depends on the surface energy of the object and the capilary forces in action on the surface of the liquid. for example mercury will not "wet" glass but water can wet the same glass.
Impressions of fingerprints may be left behind on a surface by the natural secretions of sweat that is present in friction ridge skin, or they may be made by ink or other substances transferred from the peaks of friction ridges on the skin to a relatively smooth surface.

get it wet and rub it off
The ridges and valleys in your fingerprints help increase friction between your skin and the wet glass, allowing you to grip it better. This is due to the increased surface area and contact points created by the unique pattern of your fingerprints.
To remove fingerprints from a surface, you can use a soft cloth or microfiber towel with a small amount of water or glass cleaner. Gently wipe the area in a circular motion until the fingerprints are removed. For stubborn fingerprints, you can try using isopropyl alcohol or a specialized fingerprint remover.
To remove fingerprints, use a soft cloth or microfiber cloth with a gentle cleaning solution like water and vinegar, or a commercial glass cleaner. Wipe the surface gently in circular motions until the fingerprints are gone. Avoid using abrasive materials that can damage the surface.
Attempting to burn off fingerprints is not recommended as it can cause serious injury and permanent damage to your skin. Fingerprints are a natural part of your body and serve as a unique identifier. If you are concerned about leaving fingerprints behind, consider using gloves or taking other precautions instead.
yes because they burnt their fingerprints off.
No, fingerprints do not rub off easily because they are composed of patterns of raised ridges on the skin's surface that are formed before birth and remain relatively unchanged over time. However, certain activities or conditions, like excessive washing or manual labor, can temporarily alter the appearance of fingerprints but they will eventually return to their original state.

No,you cannot.
No, you need to dry the surface (chest) before applying the AED pads, as they can slip off or become ineffective.
I had to complete a science fair project in high school about the effect of surface temp on fingerprints. My results showed that the colder the surface temperature, the more likely you are to see the fingerprint.
Highly unlikely for two reasons. (1) Unless the rock is perfectly somooth the rough surface would have very little (or no) surface for the fingerprints to adhere to, and (2) the salt water in the ocean would dissolve the oil of the fingerprints.
Probably. Any planet can have a wet surface if it's not hot.
