Today is Sunday. On Saturday morning, we were told that there would be school today because Vandita madam (the CEO) was bringing up some visitors. When that happens, there tends to be some sort of exhibition at school on Sunday and Monday becomes a holiday. They try not to rearrange the schedule too often, but they do it from time to time. On this particular day, Vandita madam's visitors could not make it that day, and school was canceled. This was known by Saturday afternoon.
Unfortunately, nobody realized we had been told there would be school, so nobody realized they would have to tell us there wouldn't be school. So we wake up and get ready for breakfast by 8 as usual, to find the place deserted.
Ah well. We have the key to the science lab. Might as well use today to test out some experiments.
As we stroll through the school gate, our eyes fall upon kids playing in the volleyball court and the area near the science lab. We ask, why are you here on a Sunday?
They answer, we're here to use the library and the computer lab. They open at 10, but we're here (an hour) early.
Okay, we say, that's good. And we go in to the science lab to work on some experiments. My mom is playing with some of the lenses, utilizing the contrast of the dark inside with the bright light from outdoors to make pretty pictures. I once again attempt the iodine clock reaction.This time, I use only the tiniest pinch of KI and a slightly larger pinch of Na2S2O3. The H2O2 seems to be rather dilute, so I use a lot more of it than I did before. And this time, I find a funnel so I can add everything at the same time.
Here, we turn around and find a gaggle of kids at the windows and doors, watching us dole out small measures of chemicals into various test tubes. Everyone that was waiting outside is now waiting by our window. Most of them say they're 6th/7th graders, which makes sense, since we haven't done many experiments with them yet, and they've been asking when we'll come to their class. Tomorrow, little darlings. Tomorrow is your day.
They skip off, not because we've told them we'll be working with them tomorrow, but because the teacher has just opened the door of the computer lab and is working on the lock for the library. So I turn back to my iodine clock and toss everything down the funnel at once.
Lo and behold, it works! Since I have no balance (there is a very good two-pan balance, but it's locked away in a glass cabinet, and looks like a treasured possession rather than a usable scale), I can't really calculate and set the clock for a certain amount of time. Still, I've got it working within about 20-40 seconds, which is perfect. By afternoon, my mom's found some litmus paper and made some dilute acid/base solutions, so everything's set for tomorrow. Time to relax a little.
