Question: What is the practical that you find the most interesting?

I really like experiments where I get to make something I’ve designed. So for example, I made a new design for the spiky surfaces I use in my work. I got to go through the whole process of sketches on paper, then designing on a computer, then making in the lab, and then finally you get to hold something that you’ve invented/made yourself. For me it’s anything that involves making something.
