Should have specified that it was PLA, since - as mentioned above - many plastics can withstand those temperatures, but PLA generally can't

Wow, that's great. Now you all can have something even more indestructible to throw in the trash, for your convenience.

Take the top off a full bottle of water and throw it in a hot campfire so it stays upright.. the boiling water will keep the plastic from melting fully for as long as it takes to boil it off.

I mean don't burn plastic, folks.

Ambitwistor: CSB: I ate the McDonald's where the coffee incident happened.  In a pretty sketchy part of town (the "War Zone").  They were shooing off a homeless guy when I arrived.


Gibson road in ABQ?  That was my McDs when I was stationed there. Last time I passed through there I had to stop by. I was surprised a large coffee is not 1 dollar there, like I am accustomed to where I live now

But then maybe we wouldn't have read the article.

Oh wait did anybody read the article?

Hahaha just kidding.

I was thinking when I read the headline, that polypropylene doesn't melt until around 130 Celsius so it holds boiling water just fine anyways.

Much cooler than it is a fully compostable plastic, or at least that is the claim.

We've had plastic containers for boiling water for a long time. What McDonald's needs is a lid that stays on.
