With Vision Supreme you can make predictions which will be printed on a piece of paper sealed in an envelope.

 

This is possible thanks to a special gimmick called "magnetic writer" invented by Pieras Fitikides. Even if the forecast is sealed in an envelope, you can influence the prediction at a time without opening the envelope and this can be done right under the nose of the spectatore. The "writer magnetic" gimmick is the first of its kind in the history of mentalism and can be used in other applications secret.
