We're all natural born liars, as presenter Dallas Campbell shows with this group of children and some cakes. But we're not very good at spotting a lie, so we try to design technology to do the spotting for us. In Monday's Bang Goes the Theory, Dallas finds out what's happening in our brains when we tell a porky-pie, and then tries to fool the latest lie detector machine.
