Помогите перевести текст!

There was a School Hobby Fair last week. We learnt a lot about likes and interests of the schoolchildren. Fifth former Petro Doroshenko has got an unusual collection. He collects rocks. “Rocks are beautiful," — says Petro. “Some of them have pretty colours. My smallest rock is the most interesting. My uncle found it near the Pacific Ocean. It’s difficult to find a rock like this.” Eighth former Borys Ivanchuk has an interesting hobby: cartoon animation2. He started this hobby when he was ten. His new cartoon is called Pencil Man. “Making Pencil Man was a lot of work,” he said. “First I had to make more than 2,000 drawings. Each one was just a little different. Then I used a camera to take a picture of each drawing. In the film the pictures move very quickly. Pencil Man looks like he is moving.” Boris is going to show Pencil Man at school gym on Tuesday at 3 o’clock in the afternoon. Don’t miss the show!
