I survived swimming with bull sharks&it was awesome!
On an engineering related note, I spent a good part of Sunday working on my EOH project for MatSE. It's not perfect yet, but I did some initial experimenting. We are making home made lava lamps and exploring how they work and how to manipulate them using different materials. It's actually really hard to get it to work, but I got some of the smaller bubbles of lava going. Here's a video!
