Disappointed.

2°C, rain then dry.
Talking to a class of 11 year olds today in a lesson on sensors. I asked them what devices they have at home with a sensor. The usual burglar alarms and security lights. Then one told us about her kitchen bin. It opens when you wave your hand over the top. Presumably so you don’t have to touch the lid.
Taking this further, another has a toilet that lifts its seat if you approach. Impressed, I asked how does it know whether you want the seat up or is it just the lid. The subtlety was lost on this group. So I said “perhaps it’s just a bloke thing”.
By now, my imagination was running with this. What happens when you go to the bathroom for a tissue to blow your nose? Like the hand-driers at work, it presumably is activated. Does the toilet lid lower itself in a disappointed way afterwards?
This would make a fun subject for animation. It’s all in the timing, the disappointment bit I mean.

This instrument is near work, on the side of a busy road. For years, I have wondered what it is. Probably a smog detector. Looking back, I couldn’t see what that light is aimed at. Is there a reflector in the distance somewhere?
