An earring from an earring pair I made as part of my Metals course senior year of high school.
Probably one of my proudest achievements -- it makes me so happy :)
On another note: today was my first day in the lab, and it was very exciting.
I may not be grad student material, but I can see the appeal in losing yourself and time to your lab work because there's many enjoyable aspects.
This is obviously all from my naive prospective, but what's so wrong with that?
