This is a role-play/improvisation where the students take it in turns to play the part of a door to door salesperson. They have to try to convince unenthusiastic buyers to purchase one of the new gadgets that is shown on the worksheets. They must try to use the notes beneath each picture to explain what it does and why it would be indispensable. The other student should ask lots of probing questions about the object, and decide to buy it or not. It's a good context for practising superlatives and comparatives along with the art of persuasion.
