[Hilarious] Funny Prank & Practical Joke Ideas (1–10)
The Bug in the Envelope

Here’s a prank I recommend for when you have a chance to hand a friend a letter: the “Envelope Bug.” This prank takes a bit of prep.
Specifically, tie a 5-yen coin to a string, twist the string up, and place it inside an envelope.
When the envelope is opened, the twist unwinds, creating a vibration that startles the person.
It’s an analog mechanism, but that actually makes it even more surprising, doesn’t it?
Transfer student prank

A prank where you lie about transferring schools or studying abroad.
It’s simple, but if you make it believable, the reveal can get really exciting.
The original idea is about studying abroad, but for middle and high school students, saying you’re transferring schools might feel more realistic.
Prank calls using only recorded audio

This prank tests whether you can hold a natural conversation with someone using only pre-recorded audio—can you pull it off without them realizing it’s a recording? Use your smartphone’s recording feature and prepare a variety of phrases and backchannel responses to make the conversation sound as natural as possible.
A good tip is to include replies that can be taken as playful responses to almost anything, as well as phrases that deny it’s a recording.
Now, how far can you go using only recordings to carry on a conversation?

A prank where you replace the contents of a canned drink with water

This prank involves making a small hole in the back of a canned drink and replacing the contents with water.
Seal the hole with tape so it’s not noticeable.
It’s easy to pull off, yet surprisingly startling for the person you prank, so it’s recommended.
100% lemon juice

This is a prank where you replace the contents of refreshing drinks like yuzu lemon or honey lemon with 100% lemon juice.
Since people expect it to be sweet, they’ll be shocked when the first sip is sour.
Set up the prank by swapping out a drink someone is in the middle of drinking, for example.
helium gas

How about using “helium gas,” a classic time-killer, for a prank? Even for a prank, getting someone else to inhale it is pretty difficult, so I think it’s better for the prankster to inhale it and make a funny voice.
There’s a lot of flexibility with this kind of prank, but it’s easier to pull off if you focus on speaking in a funny voice at just the right moment.
A lip product that makes it hard to open your mouth once applied

When your lips are chapped and you reach for lip balm, you use it without thinking and would never suspect the contents are actually a glue stick, right? And to spread it evenly, you rub your upper and lower lips together—that habit is exactly what this prank takes advantage of.
Take out the lip balm, insert a glue stick into the empty container, and push it in—voilà, you’ve got a fake lip balm in no time! Even when it’s twisted up, it looks just like real lip balm.
Anyone who falls for the prank will end up with their lips stuck together and be in for a real surprise!
