### In the lessons

In history, pupils learn about bombs in wars, such as the Blitz in London in World War II, when children were evacuated. In safety, if you find a strange object or old bomb, do not touch it — move away and tell an adult or the police; never make jokes about bombs at airports or schools, because they are taken seriously. In everyday life: bath bombs, «bombing» into the pool. Phrases: bomb shelter, cost a bomb, bath bomb, go like a bomb.
