The magician shows the audience a white rabbit standing on a pedestal.  He then shows a colorful rectangular tube empty, and with it covers the  white rabbit. 
At this point he asks the spectators a simple question: what color is  the rabbit? Everybody will say that it is white… but when the rabbit is  shown again, it is now brown! The audience, in particular children will  be initially surprised by this color change. So the magician decides to  show everybody the effect again, and makes the brown rabbit change back  to white. This time everybody will start to catch on to how the trick  works, and will start to groan… the rabbit is obviously white on one  side and brown on the other, and the magician is simply turning it  around.
But right when everybody thinks that they have understood the trick, the  magician turns the rabbit around, showing that on its other side there  is a cute little mouse!
