| Put a rubber band over your index and middle fingers. |  |
| Then secretly close your fist so that all four of your fingers are inside the rubber band. |  |
| Now show someone the rubber band and point to the two fingers which are inside the rubber band.As you're pointing you can say, "The rubber band is on these two fingers, right?" |  |
| Then open up your hand and say, "Wrong!" Can you figure out how to do this with two rubber bands so that they switch places on your fingers? |  |
