Rain

It’s a bank holiday Sunday and normal service has resumed (it’s raining) whether the weather on bank holiday Monday improves again? Well the forecast says it will.

So anyway I thought you might like an interesting fact?

Raindrops are apparently not teardrop shaped! I guess we think they are because they speed by so fast, persistence of vision (the way our eyes track things) mean that they blur together so they look long and thin….Like, er, teardrops….. or raindrops trickling down a window as they smear themselves against the glass, wetting and sliding at the same time.

So what do raindrops really look like? On slow motion cameras they resolve into little oblate spheroids….Like little tangerine shaped water droplets, that’s because air resistance squashes them up slightly in the direction of travel.

Trouble (or not) is that I’m sure people will carry on drawing them as teardrop shapes because thats how they look to us….
