Michael, you are probably correct with the any drink called for as far as the drinks tasting like what was called for.
The Tea Kettle effect; the performer pours out different (colored) drinks from the kettle and then when you take the top off the kettle, the magician removes silks. The way I used to perform it is as follows:
I had six different colored silks red, blue, green, yellow, black, and purple, and six clear glasses. Each glass was wiped with a different silk, water poured into the glass and the water would change color to the silk used to wipe it. After doing this for each glass the silks were vanished only to be reproduced from the tea kettle. One more glass was introduced and more water was poured from the kettle to fill it.
On the border of our minds lies a place where dreams and reality are one, a world of magic...
