As they walk into the room, they're greeted with a bright, white light and they have to put on dark glasses so they don't hurt their eyes.
The room is empty except at the ends: on one end, there's a big camera and a bunch of Oompa-Loompas. On the other end, there's one single Oompa-Loompa staring at a television set. All the Oompa-Loompas were dressed in weird space suits and seemed very serious. This was no funny business.
Mr. Wonka begins to explain what this room is for: television chocolate. With a few ignored comments by Mike Teavee, he explains that television takes a picture and breaks it up into a million pieces just to put it back together on the other end for people to see. He can do the same thing with chocolate, he says.
To prove it to the protesting Mike Teavee, he calls in the Oompa-Loompas, carrying a giant candy bar. It has to be giant because, like everything on TV, it always ends up looking smaller than it actually is. Makes sense.
After a few more warnings, they get started and suddenly, the chocolate has disappeared and within seconds, ended up on the other end of the room in the TV set.
It couldn't be, thinks Charlie, but Mr. Wonka tells him to pick it up, and sure enough, there it is. Same thing, just smaller.
Wow, if this works, it could mean real, live chocolate in Wonka commercials. Wonka really is a brilliant businessman. Charlie and Grandpa Joe can't believe how miraculous it is.
