The spectator thinks of a Zener symbol, the magician turns his back and scribes something on a little home made blackboard.

The spectator names the symbol thought of.

The slate is shown and the symbol that the magician has drawn matches the one the spectator thought of.

This version is completely different than ESP 2, the method is more practical and the symbol written on the board can be erased. The writing on the blackboard can be erased without hiding the blackboard. To the spectators, it is reset in a second.

This version is faster and easier than the other versions.
