I recently purchased Healed and Sealed and while I have yet to stage an actual performance, I can see the potential knock-out effect. The secret is, to use an over-used term, "diabolical". <br> <br>With the correct handling it really does look like magic happening right in your hand. And in the presentation, I found the best effect takes place with minimal handling, holding the can at my extream finger tips. <br> <br>Don't let the fact that it's a manuscript only put you off from making the investment. This one is worth the price in money and the time in working out a smooth routine. (which "suggests" itself as you work with the effect) No, it's not an improptu effect, but it's magic that appears to almost cross over into the supernatural.
