I kinda enjoyed the Exhibit held last Friday, September 7, 2007. I best like the “electric flow” part.. That’s the time wherein the whole class held their hands together and as the crew of the exhibit rotate the handle of the “electric vault”, we experienced the electricity flowing in each one of us who’s “in” the circle. I also like the symmetry mirror.. They said it was used as an “effect” that will make a person look like he/she is flying. What they did is that there’s a big mirror in front of us, then one of the crew will place half of his/her body behind the other side of the mirror leaving the other part of our symmetrical body viewed and producing a whole body cuz of the reflected image on the mirror.
Next is the “Too high and too deep well” HA! I forgot its name. XD …Well, you place your head inside a box with mirrors in top and in bottom of it. Then when you look down, you’ll see that you’re looking through a really-really-really deep well. And vice versa. It’s simply because the 2 mirrors keeps on reflecting and reflecting each other which gives a view of endless tops and bottom.
Another part I liked is the “Shadow Trapper”, what you do is that you go inside a small cubicle, then inside you’ll see a sheet of phosphorescent paper. Then for a few seconds a light bulb is lighted then you strike a pose you like. When the light bulb is turned off, you’ll see that the phosphorescent paper has formed a black image copying the pose you portrayed. It’s because the rays of light that was emitted by the light was blocked by our body producing the “shadow”. Also, the more seconds/time you spend blocking the light, the darker the “shadow” will be.
Another part of the exhibit is the “Floating Globe”. Magnets were placed in the opposite poles of the globe, then with right space and pulling of the two other magnets that stands as the holder of the globe and eventually, the result is that the globe will float. Speaking of globe, there’s a part in the exhibit wherein there’s plasma (the Plasmas are the "Fourth State of Matter" because of their unique physical properties, distinct from solids, liquids and gases. Plasma densities and temperatures vary widely.) placed inside a clear circle glass globe and when you place your finger on it, there is this electric-like current that follows your finger. It’s harmless and fun. :)
Last on my list is the Zoetrope, It is the “wheel of life”. When you place a strip of drawings inside the zoetrope's drum, spin it and look through the slots, you will see the images come to life. Of course, they are not really alive. This illusion of motion depends on two things; persistence of vision and the phi phenomenon. There are other parts of the exhibit that I didn’t mention here. But they’re sure quite kinda fun and informative. ;)
