On evaporation and blissful motion

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!
