Condiment Or Chemical Weapon? Phase Matters!

Oh sweet mother of molecules! The meme perfectly captures our chemical trauma with mustard! In liquid form? *dramatic sob into handkerchief* But gaseous form? *eyes bulging* That's chemical warfare territory!

Mustard gas (sulfur mustard) was a horrific chemical weapon in WWI that caused blistering and respiratory damage. Meanwhile, regular mustard condiment is just living its best life as a tasty sandwich topping. The phase change makes ALL the difference between "yum" and "DEAR NEPTUNE MY LUNGS ARE MELTING!"

I still have nightmares from that one time in the lab when... actually, let's not talk about that incident. The safety inspector still twitches when he sees yellow condiments!
