For a class field trip, my university took us to the zoo, which is a regular field trip spot. While most of the kids oohed and ahed at all of the exotic birds, reptiles and other animals, I had one main thing on my mind, the penguin exhibit; Penguins have consistently fascinated me, they are easily interesting little birds. Especially since they are obviously not afraid of people and you can pet them and stuff. I wandered away from the rest of my group and eventually found the sign who led to the penguin exhibit. I entered and was immediately greeted with an icy cold breeze. I immediately started shivering. Wow! I knew it was going to be cold, but I didn’t believe it was going to be this cold. I could easily see my breath in this room! I suddenly moved on over to the actual penguins, and one was right up close and center. I got to pet the glass, and pretend that I was easily petting the penguin. My breath was fogging up the glass and I was cold so I left in a hurry. When I was done, I went up to my instructor and asked how they make it so cold. My instructor explained that they had some advanced Heating in addition to Air Conditioning systems that blew icy cold cooling air 24/7 for the penguins. I was fascinated. This led me to trying this at home, and turning my own air conditioning down as far as it would go, which my parents didn’t appreciate. Sure enough, my condo became super cold from the air conditioning! I kind of became fascinated with heating and cooling units afterwards.
