Stuck underneath the large tube is a sign that comes unfurled as the dynamite is plucked from the ground. White, with large black lettering, it sits there, begging to be read. It shouldn't have been possible for it to be covered by a much smaller object, but there you go. Things aren't going to start making sense now. In fact, it's only going to get worse.

LOOK UP

Should Luke look up, he'll notice that there's a baby grand piano hanging in mid-air above him. No supports whatsoever, in clear violation of most natural laws. Natural laws are terrible, awful things, anyway, in Gabriel's opinion. Much like a cartoon, the piano will only be jostled by someone making a note of it being there, and it'll come down with an incredibly musical bang. And unlike real life, all it will do is daze as it shatters around its victim.
