Yea I have heard of this one, and seen it on numerous magic shows, one that revealed a version of the trick (performed behind a counter and with a kettle that had an elabourate wiring system), then he performed the trick again but obviously a different method, as he just had a glass and wasn't behind a counter.
I remember someone named a really exotic and weird drink, yet he still managed to produce it.
