From the Al Baker’s mind, it is one of the best and least well- known boards in the market.
These lectern and slate are handmade of a high quality wood.
It can be used to make something written appears on it magically or used for a prediction changes for another in a way that the audience cannot explain themselves.
The trick: Imagine you write a prediction on the slate, and this is shown to the audience as and advance. Then you placed the slate on the lectern backwards and you can sing the back of the slate. You ask a spectator to choose a card, but this card does not match with the prediction on the board. But when you show what had been written on the board it has changed magically for the card chosen.
