You know we use PVC, and we sheath wires with PVC for insulation.

I found a tractor fan, shock absorber, PVC pipes.

The teachers dragged giant PVC whiteboards into the classrooms.

A guy I met in my physics class made a didgeridoo out of PVC pipe.

Now, PVC is a little bit better, but still not as good as the wood that we chose.

We stripped out all the vinyl and zolatone paint that was covering up this just fantastic aluminum shell.

This time we covered the roofs of the houses, but we didn't use paper, because paper doesn't prevent the rain from leaking inside the house vinyl does.

Actually this is not a curtain. These are vinyl blinds that are integrated into the windows themselves, again with failsafe mechanisms that can be lifted such that you can completely demystify, if you chose, the operations of the theater going on behind, rehearsals and so forth.

Less well known, but following the same pattern, are efforts being mounted to question studies documenting the adverse health effects of exposure to lead, mercury, vinyl chloride, chromium, beryllium, benzene, and a long list of pesticides and other toxic chemicals. Polluters and manufacturers of dangerous products hire experts in what they call product defense to dissect every study whose findings they oppose, highlighting flaws and inconsistencies.
