Потому что у их состава поверхностное натяжение высокое (благодаря мыльному раствору и другим компонентам), выдерживающее дуновение воздуха. Поэтому воздух наполняет пленку, а когда раствор все-таки отрывается от основы, то схлопывается в шар, так как это идеальная форма, при которой жидкость стремится к наименьшему поверхностному натяжению.

Task 1. Read the text and mark the sentences. I write to friends in many countries. It's really interesting to learn about their lives and their cultures and, of course, to go and visit them! I started writing to my English friend, Tina, when I was thirteen. Tina's into sports and music just like me. We both enjoy swimming but she is fast and I'm not. Also, she listens to a lot of rock music but thate it. It's very loud! I stayed with Tina's family last summer in their house in Manchester. They were very kind and they showed me lots of different places in England. I quite liked cities of Liverpool and Birmingham. But we were in London for three days and that's definitely my favourite city! Of course it's a big and busy city with lots of great shops but it also got some beautiful parks where you can walk and sit in the sun. I enjoyed walking by the River Thames and looking at the Houses of Parliament and Big Ben, the famous clock The weather wasn't very good when I was in England and it rained a lot. But when we were in London it was warm and sunny. It was a fantastic day. I hope Tina can come to France to stay with me this year! Mark the sentences A (right), B(wrong) or C (doesn't say) 1.
