Step 1: Ask a question
I make it no secret that I prefer water resistant inks. Life is too short and I am too clumsy to lose an entire page of work to a tipped-over water bottle. But I wondered - does writing inside a closed notebook fare differently when exposed to liquid? Obviously the answer is yes when we think about errant drips or a splash quickly wiped away, but what about a complete soak?
Step 2: Do background research
I will admit, I skipped this step. But a cursory search of the interwebs did not show that anyone else has performed this sort of test…
Step 3: Construct a hypothesis
This is an important step not to skip. If you blindly barrel onward to the experiment without a working hypothesis, how can you judge the usefulness of your results?
My hypothesis was that writing on notebook pages that are pressed together would survive better than the exposed writing that I use for drip tests on ink reviews. The logic behind this is that the water between the pages would not be as mobile as drops sitting on the surface and would have a harder time dissolving the dyes.
Step 4: Test you hypothesis with an experiment
Now we get to the fun part! Doing the science. For my experiment, I took a pocket Leuchtturm 1917 and wrote on every tenth page with four different inks: Iroshizuku Yama-Budo (an ink with mild water resistance), lime green Pilot G2 (100% not water resistant), Sailor Sei Boku (pigmented), and a black Pigma Micron (also pigmented). Doing this every ten pages allowed me to see how the ink diffuses across facing and intermediate pages while still have a decent amount of ink in the book.
