Well, there is many different ways.
For example, there eyes; if the persons is looking down then they are often feeling lonely and sad, but if they are in a really concentrated stare then they are thinking.
Another example is there mouth; this is quite obvious because if they're smiling they're normally happy but you have to look closely, if it's a sort of awkward smile then they are hiding something.
They're eyebrows; If the eyebrows look loose and relaxed, the person is seen to be calm and realxed, but if the eyebrows are tense the the person is thinking, is angry about something or is concentrating deeply. You can tell which one of the emotions by the other features mentioned :)
If the person looks down and away when they ansewer you they are lying.Because this is a sign of shame.
If the person has a smirk when they ansewer,they could very well be lying.This is the sign of contempt.
You could blow on the persons face, but make sure someone else is standing there so the person might think its them...and also when you blow on the persons face you could have someone there and talk to them then blow on the persons face.
