Want to prank someone without them ever knowing? A secretive prank for you to know alone that you can do anywhere at any time?
File your fingernails over their favorite food & drink when they aren’t in the room or they aren’t looking.
Nail dust is kind of like a fine powder. You can file a nail over food or drink and the dust blends in. Move your nail over the food or drink when filing so the dust doesn’t build up in one spot making it recognizable.
Preferably you should file a clean nail and not one that has dirt underneath or isn’t fungus free. Dirt can contain disease and if your nail has fungus even if it’s being treated can be harmful. Fingernail polish or medicine on nails should not be filed either. Remember you’re not trying to make anyone sick. You’re just playing a joke. Even with clean nail filings there is still a risk of someone getting sick.
If you are thinking about using fingernail clippings, they will be noticeable but they would be a good prank to get someone’s attention. If a fingernail clipping gets swallowed it could cause someone to get choked or scratch their throat and it might do damage elsewhere in the body like getting stuck in the intestines or the kidneys.
A fingernail clipper may snag or puncture a hole in a clothing pocket, which is a perfect hiding place. A fingernail file may snag or cut delicate material when lining the pocket hiding place but if you accidentally drop the file it won’t be as noisy in the crash. A file is almost silent when dropped.
Slip the file out of your pocket when the target food or drink is accessible and file away. Nail file nail shavings in potato chip bags, remove clothespin or chip holder then replace. Nail file shavings in a drink remove lid and replace. Nail file in open junk food bags that have no clothespin or chip holder. Nail file in drinks without lids.
You may not see the full effect of your prank. The victim may eat and drink the goods later. But if you pull the prank off the victim will be none the wiser only you will know.
You may want to hold on to your food and drink, keeping a watchful eye on them if your victim does happen to discover what you did or you may become the victim of the same enduring prank.
