I am three quarters of the way through my two week precipitation experiment, which I have mostly been very good about recording. I totally forgot last night, which is a bit piss poor, to be honest. And my only excuse is that I was knackered. Oh, and we had to tighten the chain on my motorbike, which was the flappiest, crappiest thing ever. I’ve ordered a new one, and sprockets, because it’s pretty FUBAR’d.
Anyway – tonight’s precipitation was more interesting than of late; it’s been raining quite a lot, with the Met Office predicting floods because the ground is pretty saturated after the snow.
Vessel A (no funnel) now contains 20mm of water.
Vessel B (funnel) now contains 30mm of water. I also noted that the underside of the funnel was liberally coated with condensation. It’s been pretty breezy and dry today, so I am thinking that much of the water from vessel A upped and left. Either that, or my neighbours are playing silly buggers with my experiment (although it doesn’t smell of wee, so I should be thankful for that, I guess).
Evaporation interests me. I know how it happens, and why, but it still seems sort of magical. All that water contained in the air – a little like something into nothing. I love clouds too. Especially when viewed from above, because they look so solidly soft and inviting. I always find it difficult to believe that I would just plummet to a pancakey death, when it looks like I should be able to roll around in them…
But I digress. Evaporation and precipitation massively influence our planet’s climate, and temperatures. Water vapour is the most abundant greenhouse gas of all – I always assumed it was carbon dioxide. Clouds are a pretty efficient way to move all that water around. I also like to think of all the water that ever was just being shuffled around in different forms. A little like energy – it’s not created or destroyed, just changed.
So the experiment is almost over. I’m not sure how accurate my measurements have been – but I don’t think that’s the point. I think they want us to really think about experimental design, and observation, which I think I have done. I’ve enjoyed it, in a “back at school” kind of way. I’m already looking forward to the next one!
Blissful motion
For the first time in ages, I really enjoyed my journey to work this morning. I remembered why I love my motorbike. The freedom it engenders; the thrill and the beauty of the ride. It was much warmer and drier, and I flowed through bends and past imprisoned people half asleep in their boxes. It was just bliss.
Writing
I know some people who can write. I mean really write. They’re very good, and often very funny. I’m a little envious. Not too envious though – because they actually spend time doing it. I always think I want to, but never quite do. I have ideas, but don’t write them down (ha!) and I do my thinking on the bike, or somewhere equally unsuited to making notes. And my memory is pants.
I must do better. And I must do more reading!

You write beautifully, I read from top to bottom, engaged and informed. Perhaps you just need to be told you can write! You can.New comment
i love the cenotees and the invisable membrane that seperates the salty water from the sweet amazingNew comment
Thank you Jonathan, that's very kind of you
Tracey, that membrane is fabulous when you're diving - have you ever tried it? You can see a kind of shimmer. It's odd. Also, when you go through a thermocline. Which is very strange visually and physically.
