CSI @ Science Centre

Today is the day which i have been awaiting for. I went to science centre to enjoy myself in the CSI exhibition. Overall, i think it was fun and cool. Well, firstly, we had a forensic photography session. I think it is quite interesting though it can be boring after a while. After all the talking, we had a chance to do our own forensic photography. Well, we were supposed to get someone to act dead and then, we would take a walk through photo. We got grace to act as a dead person. She used her school bag to cover her face and so, we assumed that she was dead because her head got smashed by her school bag. After that, we had lunch. Right after lunch, it was something which i was very excited for. IT IS THE CSI EXHIBITION!!! WOOT!!! Well, we were supposed to do some analysis and blah blah stuff which simply says that it was related to forensic. Seriously, i think forensic is really cool but sadly speaking, i am not so good in my science and after looking at the corpse for long, i am quite disgusted. Initially, i can still tolerate the gruesome sight but after quite long, i don't think i can take it. But i believe, forensic scientists are actually use to these gruesome sights. 习惯成自然. In the exhibition, we managed to do 2 experiments. There are 4 actually but we only managed to do 2 because in the package, everyone is only given to do 2 experiments. The first experiment was ink chromatography and chemical analysis. Well, it is like something we usually do in chemistry. The second one is something much more interesting because this is the first time i am doing it. It is fingerprint analysis. Everyone of us was given a piece of transparency and we were supposed to put our thumb fingerprint onto it. Then, the person in-charge of the station will put these fingerprints into a tank, wrap it up using a plastic wrap and it was placed under the IR (In-fared) Lamp. Inside this tank, there is superglue and water. The superglue will turn into superglue fumes due to the IR lamp. The water will also turn into water vapour due to the lamp. Due to the plastic wrap, both superglue fumes and water vapour will be pushed back such that the superglue fumes will be on the transparency to make our fingerprints visible. The main use of water prevent the tank from overheating and also to pace up the experiment. Without water, we might got to wait very long. As we were waiting, the person in-charge of the station told us about the types of fingerprints. There are 3 most common type of fingerprints in the world which are whole whorl, plain arch and loops. There are other types of fingerprints but i don't think i am going to name them out. Then, i started looking at my fingers and i realised i got 5 whole whorl and 5 loops. Cool... But sadly, i didn't manage to go and do the blood analysis experiment. But nevermind. After this, we went to do some fake wounds. We were supposed to do some fake wounds on our model and it must be very gruesome such that it is seen to be a very realistic wound. Sounds complicated but it isn't. Well, grace was our model. 可怜的 Grace, she got to always sacrifice herself. Jia wei was very good at doing make-up man! She managed to help grace make up a bruise on her face such that it looks like grace just got bashed up by someone. Then, i made a burnt wound on jia wei's hand. Just looking at it, it does not really seem that gruesome but on the camera, it is much more gruesome. And grace's bruise seem to be more serious on the camera too. That was the last programme and then, we went home. Initially, this whole event should end at 5.00pm but it was delayed until 7.15pm and by the time i reached home, it was 7.30pm. However, i enjoyed myself. I think that this CSI exhibition is really very cool and very fun. If you have a chance, you should go and try out being a forensic scientist. Although the entrance ticket isn't cheap ($16), i think it is quite worth it since you will be able to learn something new and most importantly, have fun and enjoy.
