This worked in a similar way to a hotseat, but without the live element. During the interview the children got to put their questions to Sammy, a teenager from Ghana who had witnessed the terrible floods which affected an estimated 260,000 people.

As part of the interview Katy M asked: "Do you ever feel angry or upset that you can't do anything to help the people in trouble?"

Sammy said: "Yes, I get very upset when I see my friends suffering and I don't have enough resources to help them."
