Swap the mud shampoo with real mud

Would they notice if you swapped the mud shampoo with just plain mud?!

Swap the mud shampoo with real mud

Here’s a prank where you replace the contents of a commercially available mud shampoo (sold by various brands) with real mud.

It’s super easy to do: take a store-bought mud shampoo bottle, fill it with regular mud you can find anywhere, give it to your target, and enjoy their reaction when they use it.

Never do this at public bathhouses, since it would bother other customers.

Set it up in someone’s home bathroom instead.

Please follow manners and rules while enjoying your prank.

The shock pen you often see on variety shows: when you click to extend the tip or start writing, zap! An electric shock runs through it and surprises whoever’s holding it—it’s the classic prank gadget! Nowadays you can easily get one online for under 1,000 yen.

As shown in the video, it’s an easy prank to pull off with simple setups like, “Can you sign here?” or “Hey, draw something for me.”

Contents of the suitcase

[Prank] I swapped the contents of their suitcase with a bunch of babies lol

Contents of the suitcase

Let me introduce a prank where you replace the contents of someone’s suitcase with a bunch of realistic baby dolls.

It’s exactly what it sounds like.

Prepare several baby dolls, take out the target’s belongings from their suitcase, swap them with the dolls, and enjoy their reaction when they notice.

The sight is pretty psycho and surreal, so the impact is huge.

If you record it as a video, it might be something everyone can look back on and laugh about later.

Change the wallpaper

[Monitoring] What if your partner’s phone wallpaper was another female YouTuber…

Change the wallpaper

What kind of image do you use for your smartphone’s lock screen? Some people choose landscapes like the sky or the sea, others pick their favorite celebrities, characters, or photos of their pets—everyone’s different, right? So if that lock screen suddenly changed to a “What on earth is this?!” kind of picture, you’d be pretty shocked! If a landscape photo just turned into a different landscape, or a dog became a cat, you might not get much of a reaction.

So when you do it, go bold! Try something a bit creepy, or a photo of some random person that makes you go, “Who is that?” There are all sorts of fun things you could try!

Fake blood during shampoo

When I let fake blood drip while shampooing, it caused an insane panic lol

Fake blood during shampoo

This prank, using fake blood, is guaranteed to cause a major panic! While the person is shampooing, you drip the fake blood so they feel, “There’s so much blood, but I have no idea where it’s coming from!” It’s perfect for trips with close friends or when you’re helping someone with a DIY hair dye.

However, some people may be shocked by the sight of blood, so make sure to check carefully in advance that this won’t be an issue.

If they start to panic too much, reveal the prank quickly.

Please carry it out with proper caution!

Replace the inside of the toothpaste with chocomint

[Prank] Will they notice if I swap the toothpaste with chocolate mint!?

Replace the inside of the toothpaste with chocomint

When you say your favorite ice cream flavor is mint chocolate chip, people always respond, “Doesn’t that taste like toothpaste?” Right? Here, we’re introducing a prank that turns that exact trait on its head! If you swap the contents of a toothpaste tube with mint chocolate chip ice cream, will they notice? Since the scent is very similar, they probably won’t realize until they actually start brushing! Do some stealthy prep, and try it out when you’re going on a trip with friends, for example!

Infinite Shampoo

[Prank] I hid shampoo in the shower head and made it an infinite shampoo

Infinite Shampoo

The “infinite shampoo” prank is something you often see on YouTube! While someone is rinsing out their shampoo, you secretly add more shampoo onto their head from above, so no matter how long they rinse, they can’t get all the suds out—a low-key but surprisingly effective prank (lol).

There are elaborate methods where you rig the shampoo inside the shower, but the simple approach of just pouring shampoo over their head is easier and does the trick!
