A Capital Prediction

Effect: A capital city is chosen. Inside an envelope which has been on full view is a paper naming the city selected.

Secret: Write a capital city on a piece of paper and seal it in an envelope. Capital cities are called and you write them down on slips of paper which are folded and dropped into a box. In fact you write the same name on every slip – the name of the city in the sealed enveloped. Someone picks a slip and calls out the chosen city. The envelope is opened to show you knew which city would be chosen.
