So that was my weekend in a nutshell, or should I say seashell? There are other things I could share about last weekend, but they seem to lose their appeal a week after they have happened! Sorry if this blog seems choppy, but I have been writing this on and off at school during my breaks, just to get it done! If anything fun happens to me this weekend I promise I will try to write about it by Monday! Have a good weekend everyone!

death by fan
Fan death is an urban legend that originated in South Korea, but has since spread to other countries in the Far East. The belief is that an electric fan, if left running overnight in a closed room, can result in the death (by suffocation, poisoning, or hypothermia) of those inside. This belief also extends to air conditioners and the fans in cars. When the air conditioner or fan is on in a car, some people are apt to leave their car windows open a crack to avoid "fan death." Fans manufactured and sold in Korea are equipped with a timer switch that turns them off after a set number of minutes, which users are frequently urged to set when going to sleep with a fan on.
The belief in the myth of fan-death often offers several explanations for the precise mechanism by which the fan kills. However, as explained below, these beliefs do not stand up to logical and scientific scrutiny. Examples for possible justifications of belief in fan death are as follows:
- That an electric fan creates a vortex, which sucks the oxygen from the enclosed and sealed room and creates a partial vacuum inside. In reality, the air pressure at any point in the room varies less than it does during a storm.
- That the fan uses up the oxygen in the room and creates fatal levels of carbon dioxide. There is no actual conversion of oxygen to carbon dioxide happening; unlike a candle, the electric motor in a fan does not alter the chemical composition of the air (apart from creating some ozone if the motor uses brushes, and outgassing from the materials).
- That if the fan is put directly in front of the face of the sleeping person, it will suck all the air away, preventing one from breathing. However, as can be easily verified, it is possible to breathe with one's face in front of a running fan.
- That fanblades chop up air particles (i.e. oxygen molecules) so that the air is no longer breathable, thus resulting in suffocation. If this were true, regular fans could be used to create chemical reactions. However, air ionisers do turn a very small amount of oxygen into unstable ozone.[1]
- That fans cause hypothermia. As the metabolism slows down at night, one becomes more sensitive to temperature, and thus supposedly more prone to hypothermia. If the fan is left on all night in a sealed and enclosed room, believers in fan death suppose that it will lower the temperature of the room to the point that it can cause hypothermia. Empirical measurements will show, however, that the temperature in the room does not fall, at least not due to the fan; if at all, it should rise slightly because of friction and the heat output of the fan motor, but even this is generally not significant. Fans actually make one cooler by increasing the convection around a person's body so that heat flows from them to the air more easily, and by the latent heat of vapourisation as perspiration evaporates from the body. Furthermore, hypothermia occurs only when the body's core temperature drops below normal, and will not generally be caused simply by cooling of the skin or decrease in the body's surface temperature.
- Often, believers claim that a combination of these factors is responsible. For example, it might be claimed that the decrease in oxygen and increase in carbon dioxide, in conjunction with some degree of hypothermia, could prove fatal to a sleeping person.
- The heat wave which has encompassed Korea for about a week, has generated various heat-related accidents and deaths. At least 10 people died from the effects of electric fans which can remove oxygen from the air and lower body temperatures...
- On Friday in eastern Seoul, a 16-year-old girl died from suffocation after she fell asleep in her room with an electric fan in motion. The death toll from fan-related incidents reached 10 during the past week. Medical experts say that this type of death occurs when one is exposed to electric fan breezes for long hours in a sealed area. "Excessive exposure to such a condition lowers one's temperature and hampers blood circulation. And it eventually leads to the paralysis of heart and lungs," says a medical expert.
- "To prevent such an accident, one should keep the windows open and not expose oneself directly to fan air," he advised.
When informed that the phenomenon is virtually unheard of outside of their country, some Koreans have suggested that their unique physiology renders them susceptible to fan death (despite the fact that Korean Americans born outside Korea who have never heard of this phenomenon sleep with fans on and do not suffer any ill effects).
So as crazy as this sounds, people here really do believe this!! This weekend I went to the east coast of Korea and stayed in a hotel. The Korean we were with insisted we turn off the fan that night because of fan death. Adam and I basically laughed and said, "You aren't serious, right?" Well go figure, he was! He acted like it wasn't a big deal and said, "Ok, we can leave the fan on." About 30 minutes later when he thought we were asleep he got up and turned off the fan! How funny is that?? Also, I have another blog that I will be posting soon with some amazing pictures from this weekend!!

it's about time!
Here is a little shop in Insa-dong that sold traditional Korean pottery and ceramics. I think this one might have even been an antique store, but I am not sure.
On April 5 we celebrated Arbor Day at our school. Arbor Day used to be a national holiday in Korea and all schools used to be canceled. A few years ago the government decided to recall that day as a holiday and now it is just another school day. However, our school principal wants to keep the tradition of planting alive so we celebrated it as a school. All the kids brought in plants or seeds to be planted. Since we don't really have a yard at school to plant in we used big bins. My kids especially enjoyed digging in the dirt and getting dirty! This past week I also had a parent observation day. The parents came into school and met with the principal and talked curriculum and then observed me through camera and microphone. I was nervous because my kids can be very energetic and rambunctious, but I think the observation itself went well, despite the fact that someone threw up all over the bathroom during that time, which then somehow managed to clog the toilet and made it overflow all over the bathroom floor so I had to stop my lesson to get someone to clean up the huge mess!
Welcome to the jungle! Here is a picture of the three of us about to enter the "reptile section" of the aquarium.
Here is a picture of some tiny jellyfish at the aquarium.
Here is a Spider Crab (I think). This is a crab found near the waters of Japan mostly (once again, I think, but I am not positive). I do know that it is the largest crab in the world. I am not sure if you can tell from the picture, but this crab is huge! It was probably about 3 feet across. The biggest one on record is over 6 feet long, how about those crab legs for dinner!
Here is a neat picture (thanks to Adam) of Techno Mart. Techno Mart is a huge store! 6 floors of any kind of technological item you could imagine...TVs, cell phones, cameras, appliances, computers...etc. On the top floor is a food court, a couple of coffee shops and a huge cinema complex. This picture doesn't even do the store justice...just try and imagine the fish market picture I put up a on my last post and switch the fish over to appliances and whatnot...That is how crazy this store is!
