[Prank] Surprise Ideas Recommended for School Culture Festivals (1–10)
Prank from behind

It’s a classic prank.
Since it’s a prank you do with your whole class at school, you can’t set it up alone—but doing it together makes it really fun.
After the morning assembly or after everyone stands and bows at the start of class, everyone just turns around to face the back and sits down like that.
The teacher will probably be flustered, but this prank is proof that the class loves their teacher.
If you’re the teacher and your students pull this on you, please forgive them.
Air horn prank

The horns on large trucks can be really startling, right? This video is packed with clips of people being surprised by air horns.
It’s an over-the-top prank that’s guaranteed to annoy everyone around, but watching it kind of makes you want to try it yourself.
Terrifying clown

You often see them on shows that feature videos from overseas, right? You don’t actually get many chances to see clowns in Japan to begin with, but if a clown holding a hammer or an axe appeared right in front of you, it’s understandable that you’d want to run away.

From argument to a full-on fight prank

This prank might give you a bit of a scare.
The person being pranked would probably be quite confused.
Since this prank also tests everyone’s acting skills, I’d love to see it done among people who are very close.
Please choose your target carefully and carry it out in a way that won’t escalate into a real fight.
iPhone destruction prank

A plastic look-alike often called a mock unit that resembles an iPhone is a realistic option.
Since smartphones are also valuables, be mindful of the place and the person, and try it only with someone who understands jokes! It might be fun to record it and watch later.
Rap prank

This is a classic prank where you stick plastic wrap across the classroom entrance so that anyone who walks in without noticing gets it stuck to their face, but during an event people might be more likely to fall for it than usual.
Try to prompt them to run in.
Death Sauce straight on grapes

Do you know “Sonomanma Grape,” the gum that comes with three pieces, one of which is sour? Here’s a terrifying prank where someone loads that gum with death sauce! Even the one sour piece can do a fair bit of damage, but it’s nothing compared to death sauce, so many people let their guard down a bit.
That’s exactly what this scary prank exploits! You carefully open the bag so there are no traces of tampering, then use something like a syringe to inject death sauce into one of the pieces.
Next, you gather people with a casual call like “Let’s test our luck together!” or frame it as some kind of penalty game.
After that, you open the bag as usual while making sure it doesn’t look like it was already opened, and hand the death-sauce-filled gum to the target of your prank.
With their guard not fully up, it’s exciting to imagine what kind of reaction they’ll have!
