I'm sure you've ever travelled by car and it's started to rain.

1. The following image is the patent drawing of the first windscreen wiper, invented by Mary Anderson, which she herself registered in 1903. Obviously, its shape is very different from today's windscreen wipers. However, there are still parts that are very similar to the original ones Mary Anderson devised. Which parts have remained virtually unchanged since her conception?
