Jim Steinmeyer's version, "Hospitality," is sold by David Charvet. It's a great routine and the drinks are all real and can be given out at the end.

Here's his description:
"IMAGINE ... From an unprepared milk carton you can pour plain milk, chocolate milk, strawberry milk, PLUS cola, orange juice, seltzer, grape juice, tomato juice and lemonade (or any other drinks of the magician's choosing, including alcoholic beverages, if desired.) All of the drinks are REAL and may be tasted by the audience. No "essences" or flavorings used. A POWERFUL five minute routine filled with real mystery and audience participation. This is an effect that audiences talk about!
Our version of this effect has been featured by many top professionals around the world, including Lance Burton in his Las Vegas stage show, Luis DeMatos on his network TV special in Portugal, and the late Doug Henning in his final personal appearances.
Can be performed practically anywhere. Living room, platform or stage. Minimal set-up (about 5 minutes.) Everything (except the drinks) packs into the custom-crafted bar case. 24" x 16" x 7" when closed. Laminated finish resists spills and wipes clean. No table base supplied (use a waiter's stand available at any restaurant supply store.) All props supplied. No expensive refills. Get everything you need for future performances at any grocery store.
Comes with video instructions and booklet.
Custom crafted by Mark Evans.
