Launching a Lifeboat
When a boat is in trouble, a call goes out to the lifeboat station. Pagers sound. The crew are volunteers, so they stop whatever they are doing and drive to the station. Most arrive within six minutes. They pull on drysuits and lifejackets and climb aboard. The boat slides down a ramp into the sea and the engines start. At sea, the crew look for a flare, a light, or a shape in the water. Once they find the boat, they take the people off first and the boat second. A lifeboat can right itself if a wave rolls it over.

How Glass Is Recycled
Glass is unusual. It can be melted and remade for ever without getting any worse. Bottles are first sorted by colour. Clear, green and brown glass have to be kept apart, because you cannot make clear glass from green. The glass is then crushed into small pieces called cullet. Metal lids are pulled out with a magnet. Cullet melts at a lower temperature than the raw materials glass is made from. That means recycling glass uses less energy than making it new. The melted glass is poured into moulds and blown into new bottles.
- 1. What is a "mould"?
- 2. What is "cullet"?
