Friends of The Magic Café, I would like to explore a discussion on which the magicians can do for the following situation:

I was contracted, to do a small presentation, in a restaurant where who negotiated asked for me for me to do some magic transforming the alliances of silver of the couple in alliances of gold, (engagement request).

I made the following effect, I caught the alliances of silver of the two put on the "flash paper" I wrapped the alliances and when putting fire the flash paper it adds appearing like this the two alliances of gold giving the impression that the fire transformed the silver alliances for gold. All this setting up a plot, putting a history of the because I was putting the alliances in the paper, and doing in first place the mental magic, in other words, the psychological fantasy.

I would like to read some ideas on what can be done with that approached theme.
