It's hard to believe that a small item (the paddles are only 3" (7cms) long) can create such wonderful magic. Starting with a little bat which is blank on both sides, one spot appears and then multiplies. Introduce a second bat and the spots start jumping from one bat to the other. It looks like real magic! At the end, you are back where you started with one blank little bat. Perfect magic at your fingertips.
Always ready. No re-set. Virtually nothing to carry. Outstanding reactions!
