Tongue Tastes

The tongue tastes are what I'm aiming for in my experiment, I am trying to trick the sense of taste and sight. People will look at a bag of fruit bursts, unwrap a single fruit bursts. But then once they taste it they will get nothing what they expect and it gives them a shock on whats really the flavor. I will try and make some sweet, salty, bitter and sour lollies. Then also i might add a surprise flavor.
