Science and Technology Unit 6. Who invented that? What's so funny? I can't concentrate on my work if you keep laughing loudly like that. I'm sorry. It's just that I'm reading this article in Science Today magazine about some of the unusual things that people have invented. These inventions are incredible. Okay, tell me about some of these inventions and let's see if I think they're as funny as you do. All right. The first one is a ladder for spiders, a thin, flexible rubber strip which attaches to the top edge of the bath. I wonder how long it took someone to invent that. Another inventor has designed a portable seat that you wear on a belt around your waist. In this picture it looks like a big plastic cushion. Well, that is very unusual. But who would want to walk around with a portable plastic seat hanging from their waist all the time? Another unusual invention is this one. Look, it's a car plate that indicates whether the driver is a man or a woman by using different colors on either side. There's one color for males and one for females. What's the point of that invention? The inventor says that other road users will change the way they behave. They will become more polite if they know a woman is driving, so there will be fewer car accidents. Huh, do you really think that will happen? That's completely unbelievable.
