Use two Post-It notes or piece of papers. In bold text write the words ‘AN IMP’ (make sure to have a small space between the AN and the IMP) on one and ‘RESSION’ on the other.
Show it to your chosen friend, family or colleague. It won’t mean much to them as it stands, you can even shuffle the words around, place them in different order or on top and below one another. Just don’t reveal the twist just yet.
