Chemistry Error on Seinfeld

June 29th, 2015

Something didn’t quite look right when I saw this scene from ‘Seinfeld’ in real time:

Closer inspection of the fire diamond reveals the flammability rating of the paint thinner to be 8:


That’s pretty impressive, considering the maximum score is 4 on the NFPA 704 standard. If acetylene is a 4, I wouldn’t want to be driving around town with an 8 in my trunk.

For those curious, the episode is ‘The Pothole’ from Season 8. The IMDB page for the episode already lists the scene as a goof.

Longtime readers will remember that this is not the only time Jerry Seinfeld has used chemistry for laughs.

    Oh, come now…these are the sorts of hard-hitting posts that readers of this blog have come to expect. We’re taking *Jerry Seinfeld* down a peg! He obviously knows nothing about the standards of the National Fire Protection Association!
