Experimental method

Slightly different ‘toon this week: the ageing of Kevin, also known as the experimental method.

I originally made this to go in the life in the lab book, but currently have removed it. What do you think?

FYI: Chpt 1 of the book covers the peach coloured bit, chpt 2 the blue, chpts 3 and 4 and 5 the yellow, Chpts 6, 7, 8 and 9 the green. However, there is some other stuff in the book too (see contents in this blog post)
