Well, I'm a bit behind on the times, so this is my introductory post, I suppose.
So here I am, Jessi, the third and final freshman of the bloggers. You can find a somewhat decent description of me on my About Me page. It's pretty exciting to finally blog; I'm not sure that I have some sort of theme, but hopefully you'll find my posts interesting in any case. Rather than list more activities and things that I do, I think that my introductory post will begin with a story of two weekends ago. Let me know if you like anecdotes, or if you'd prefer more informative posts. I'm probably going to be mixing it up, but I like this story.
We were in the EDS lab, testing a circuit that was intended to model the heated metal fin we had just performed various tests on. After scrounging around for resistors of the right size, the circuit was complete and behaving as it should. We had recorded voltages, downloaded data, and closed our laptops with the knowledge that we had good lab data. Saturday night was ours to seize- the lab had been conquered. Just as we were about to leave, though, two upperclassmen entered carrying bowls and spoons. It was time for ice cream.
We just had to get the liquid nitrogen first.
I had heard of this being done before. When I was at MIT for their CPW, Random Hall had a big tank full of ice cream supposedly made in this fashion. When we were given our dishes to make sundaes there, though, it seemed anticlimactic. The ice cream had been made already, which took a great deal of the fun away. Now I had my shot to finally see the process in action. Plus, liquid nitrogen is pretty nifty.
Up in the robotics lab, ingredients had been assembled. Our group of four was rounded out with three more, and we excitedly waited as two went upstairs to obtain the final ingredient. Spoons were divided up and ingredient levels were checked. Even being a bit short on vanilla, we were pumped. (Disclaimer: We were given permission to take the liquid nitrogen by the professor. Also, we had gloves and such. You probably shouldn't do this on your own because liquid nitrogen is really cold.)
They came back, and we mixed the everything together. Slowly we poured the nitrogen over the mix, watching as plumes of vapor snaked out from the bowl. Soon even the strongest of us was having issues stirring the now-frozen ice cream. Deciding to skip the whole "separate bowl" thing, we pounced. It might have been lacking a bit of vanilla, but that ice cream reminded me just how excellent being at engineering school can be.
