Warning: NSFW (Unless you work at a University and part of your job is to watch stuff like this and post it on a blog).
The highlights of this have been around all week, but most of the clips are just Bill Nye the Science Guy saying "motherf***ers. But this segment on Last Week Tonight really does a nice job of simply explaining how Carbon Pricing works. If you don't want to watch the whole thing, just fastforward to the 9:27 mark or so, and sit back and enjoy.
Bill Nye explains the Law of Demand from 10:21 to 10:37.
Now if I can just figure out how to use this in class without trigger warnings.
