(Shiny long hair~)
(Who is this lady drying her hair with incredible beauty?)
(The girl group with full of charms, Fiestar's Jei!)
Yeom Kyung Hwan: Jei! Jei!
Yeom Kyung Hwan: Could you dry your hair gently?
Yeom Kyung Hwan: Because of you, the house is full of your hair!
YKH: Look at these hairs fallen off!!
YKH: You don't even clean!
YKH: Why don't you just tie your hair at home?
Jei: Oppa! Stop nagging me! Why do you always scold me?
YKH: To whom am I supposed to do that then?
YKH: Are these my hair? Are you making fun of me?
YKH: You've got hair and I don't! Are these my hair then?
YKH: All these hairs at home are yours regardless they are short or long!
Jei: Okay, okay!
Jei: Stop it! I will clean it up!
Jei: He's nagging me every day!
Jei: So nagging!
Jei: Happy ya~! Would you like to be all dried up?
Jei: It's cold outside so your hair should be dried up completely.
(Jei's adorable pet dog, Happy is drying the hair very carefully.)
YKH: Dog hair! Dog hair!
YKH: Jei! You should clean up your hair and dog hair completely before you go out, okay?
Jei: Okay, okay! Stop nagging!!
Jei: It's all done~
Jei: Happy. Would you like to go for a walk?
Jei: Let's go.
(Jei is heading outside while forgetting to clean up hairs)
(Just in time, Uncle Byeong Seo is visiting the house)
Choi Byeong Seo: Oh, it's you, Jei~! / Jei: Yes.
Choi Byeong Seo: Are you going somewhere?
Jei: I'm going to walk my dog.
Choi Byeong Seo: Is Kyung Hwan inside? / Jei: Yes, he is.
CBS: Okay, go ahead. / Jei: Okay. / CBS: It's cold, be careful! / Jei: Yes!
(Several days later, Jei is trying to dry her hair with hair dryer)
Jei: Uh? Why is this so weak?
Jei: It's probably broken.
Jei: Well, I will just get a new one.
(But right at the moment)
YKH: What happened? What's going on??
YKH: What's the matter? What should we do??
(Jei was hospitalized immediately but she suffered substantial burn injury)
(Let's stop for a moment)
(Accidents and incidents caused by hair dryers are reaching up to 30 times a year.)
(Recently in Choongnam Asan, there was an accident to a man who suffered severe burn injury to his hand caused by hair dryer explosion.)
(Also in Seoul Yangchon-Gu Mok-***, a short-circuit caused by hair dryer inside bathroom caused the fire burning down part of interior of the house)
(Then, this is the question right here)
(What caused the hair dryer to explode?)
(The reason for the hair dryer to explode is that hair and dust are trapped and stuck in the vent.)
(To find out how dangerous the hair dryer is by having the vent stuffed and the motor malfunctioning)
(let's do some experiments)
(For safety, it will be done with safety personnel standing by)
(For all of our safety, special guest is here to participate in this experiment)
(Ms. Jang Yoon Jung. Thank you for participating)
(We began experiment with assumption that hair dryer is being stuffed by hair being sucked into it)
(Finally, let's begin)
(The hair dryer blows hot air as soon as the switch is turned on)
(After two minutes, hot air out of hair dryer gets up to 200 Celsius degree (392 Fahrenheit))
(The hair dryer is continuing to operate until 30 minutes now)
(The hair dryer is making sparks with burning noise while it is running)
(At last, the hair dryer is causing a flame and spreading to burning fire)
(Not long after the hair dryer burnt into flames, it starts to melt down to demolition)
(If it was being used by a person, it is a dangerous moment that can lead to not only property damage but loss of human lives)
Professor Kim Chan Oh: Hair dryers can trap hair and dust
Professor Kim: and therefore the vent at the end can be stuffed.
Professor Kim: It will cause heating coil to overheat and start the flame.
Professor Kim: In result, it will cause fire or even an explosion.
Professor Kim: Therefore, before you turn on the switch, it is necessary to check and keep the vent clean at all times.
(There are well known ways to fight sleepiness)
(Indeed, we will do some experiment to find out which is the most effective way to fight sleepiness)
(We will be joining with rising new idols, History and Fiestar members)
PD: Do you guys drive often in regular days?
Dokyun: I drive sometimes.
Dokyun: I drive regularly but not often.
(Members participating in this experiment have driving experience ranging from as low as 3 years to 6 years)
Dokyun: I get sleepy the most when the heater is on and when I get stuck in the traffic.
Linzy: I think I get really sleepy in 30 minutes to 1 hour after I eat meals.
(First, we prepared food that will make four members sleepy and instruct them to have a meal)
(Members are enjoying their lunches)
(In 30 minutes after the meal, the experiment will get started at the highest point of drowsiness)
(We have given each member the most popular ways to fight sleepiness: chewing gums, coffee, wet towels and music player with earphone)
(We also have prepared driving simulators for this experiment)
(Finally, we set the temperature at 23 Celsius degree (73 Fahrenheit) which will induce the drowsiness the most)
(Okay, let's start driving)
(Members are driving with a method that they have selected)
(Things are calm and relaxed for now)
(But after 10 minutes behind wheels)
(Their eyes start feeling heavy)
(and Jaeho starts falling asleep)
(and there's an accident)
(Jaeho who used wet towel was the first one to have an accident)
(After that, Dokyun with coffee and Hyemi listening to music)
(had accidents after drowsy driving)
(Finally, Linzy who was driving with chewing gums was able to drive safely for the longest period of time)
Insurance Associate Director Lee Deuk Roh: Getting behind the wheel with drowsiness and tiredness is very dangerous.
Director Lee: Many people prefer to have caffeinated drinks or coffee to fight sleepiness.
Director Lee: Excessive intake of caffeine would induce excitement and anxiety so it could be rather dangerous.
Director Lee: And when you move your jaw while chewing gums or eating snacks
Director Lee: it can stimulate your brain to fight off sleepiness.
Director Lee: But it is not recommended having a complete faith on it.
Director Lee: The best way is to pull over and have a nap for about twenty minutes.
