Quote 22
Mr. Wonka handed each of them a pair of dark glasses and said, "Put these on quick! And don't take them off in here whatever you do! This light could blind you!" (26.1)
Yikes. This sounds just plain dangerous. It's interesting that a place so wonderful has so many of its own kinds of hazards.
Quote 23
"No, no! Stop! Hold everything! You there! Mike Teavee! Stand back! You're too close to the camera! There are dangerous rays coming out of that thing!" (27.17)
Does Mike Teavee care about dangerous rays? Of course not. After all, television has made his brain "AS SOFT AS CHEESE" (27.77). Any kid with his wits about him probably wouldn't go near a camera emitting dangerous rays.
