Look! It's my DNA.

That floating thing is my DNA.
Haha. Extracted it during the lab session today from my cheeks.
Yeah, it was actually a bit disgusting having to swirl the salt water in our mouth for 30s and then spitting it back into the cup. And the cup was quite small! Have to spit properly if not spill everywhere very er xin ah... Plus it was my last lab session today. Lab sessions are actually quite enjoyable since it's interesting and there's no need to prepare beforehand. Just gotta finish a report after every session. Aww, i'm going to miss the lab sessions. I mean, it might even be my last time in a lab...
