How Much Is the Fine for Doing This on a Bicycle? Take the Quiz!

If you answer incorrectly, you’ll face a punishment where a large amount of water falls from above.

The participant wears an intelligent and sophisticated outfit featuring a navy shadow-stripe suit made of 50% wool and 50% polyester, paired with a light blue blouse.

This quiz challenge is also available on YouTube in a different camera angle version.

In the second half, we test the performance of an action camera. The model films herself while playing basketball, makes a successful shot, then slides down a waterslide and jumps into the pool.

She also dives down to the bottom of the pool to collect four stones.

The footage was recorded using three different settings:
① Normal mode
② Image stabilization mode
③ Horizon leveling mode

The same course was filmed with each setting to compare the differences in video quality.

Highlights include the surprising reaction to a large amount of water pouring down from above, as well as the exciting moment of entering the pool from the waterslide with a natural reaction!

We experimented by adding Mentos and various other candies to cola, creating explosive eruptions.

We also tried a challenge where the cola bottle was placed on top of the head before the eruption, resulting in the entire body being covered in cola...

Finally, we poured the remaining flat cola over ourselves with a bucket to bring the experiment to an end.

In the pool, we explored the bicycle laws that changed in April 2026 through a quiz-style challenge.

The process involved repeatedly diving down to the bottom of the pool, picking up quiz cards, and answering the questions. The underwater scenes were filmed with an underwater camera.

The Mentos cola experiment is a “fun and exciting” segment, while the underwater quiz is a “learning-focused” segment.

This video combines entertainment with the opportunity to gain some knowledge while enjoying the experience.

We hope you enjoy the atmosphere and unique challenges!

We tested how far a water gun can shoot by measuring its actual range.

Depending on the distance, the water can reach the target, and we also confirmed moments where getting hit results in getting completely soaked.

The participant wears a gray × pink striped jacket with a plain black skirt (a wool–polyester blend) during the shoot.

Next, we conducted a performance test of an action camera inside the pool.

• Stabilization test: walking shots and filming while using a float
• Depth test: underwater diving shots
• Horizon leveling test: stability during jumps
• Light performance test: brightness underwater

All footage was filmed with self-recording by the model, featuring both wide and close-up angles.

In the diving and surfacing scenes, you can repeatedly see water dripping off the hair as it sticks to the face when coming up from underwater!

The bicycle rules were revised in April 2026.

The suit worn in this video features a navy shadow-stripe pattern and is made of 50% wool and 50% polyester.

In this challenge, we present a quiz about how much the fine would be for violating these rules.

If the answer is incorrect, a large amount of water falls from above as a punishment challenge. A different angle of this scene is also available on YouTube.

After that, we tested a damaged float by applying strong tape to see how long it could withstand use.

The float was actually used in the water to examine its buoyancy and durability.

In addition, we played with a killer whale float, jumped into the pool, and swam around while enjoying various water activities!

After playing with water balloons, we jumped straight into the pool.

Fully submerging in the water, we then moved on to filming a water rescue-themed challenge.

The suit worn in this video features a black houndstooth pattern and is made of 50% wool and 50% polyester.

Next, we repeatedly dove down to the bottom of the pool, picked up “conspiracy theory quizzes” placed underwater, and answered the questions.

The footage includes self-recorded underwater scenes, offering both wide and close-up angles for a variety of perspectives!

After playing with water guns for a while, we recreated the traditional hot water pouring festival by pouring hot water over ourselves and getting completely soaked!

The suit worn in this video features a black houndstooth pattern and is made of 50% wool and 50% polyester.

After getting cold, we warmed up in the bath while talking about hot springs, diving underwater, and enjoying the relaxing atmosphere.

We then went outside for a walk around the open area before returning to the bath, warming up again, and spending more time underwater!
