Oh —— you mean they've superglued themselves to the wall?
Are they aware of the centuries of Big Industrial Chemistry needed to come up with superglue? It's hardly a fundamental substance and I doubt if any of its primary ingredients can be produced without immense fumes. They worry about "oil" but do they know whether a hundred year old car would have more fumes exiting its exhaust than came from the factory making it? (ask them for quantities) What about rare earths used in fancy magnets? (ask them about % yields from ore) I'm not making the claims so needn't have those answers to hand. Hand! Geddit?!!?!??!?!??!?!
OK, I've recovered from that now – yesterday I was talking to someone about how much fuel his vehicle used. That is to say he was talking to me about it. I was impersonating a deaf person. But he did say something like, "You'd think they could come up with something better than blah, blah, etc.," so I said, "Yes: centuries ago: clockwork." And I'm sure with development of metals throughout the industrial revolution we ought to be able to make a pretty good clockwork car by now.
It doesn't look very comfortable though. Wouldn't it be more convenient to concrete their feet into a hole and sit on a chair?
