Here in the USA, south Mississippi, it's fucking hot as hell as well!

And unfortunately, we're borrowing my mom's car for now, waiting for a part we ordered for the truck to come in. Mom's car has 4 windows, but only the front passenger window goes down, and no air conditioner.. 🥵

I've taken to bringing a cooler with us, with bare minimum of 2 bottles of frozen fresh water, plus 2 bottles of frozen saturated saltwater.

Why frozen salt water? Well it's definitely not for drinking, that's for sure. But frozen saltwater freezes at like -10⁰C, which makes them excellent ice packs to keep things in the cooler extra cold for around 6 hours or so...

Stay cool out there everybody!

    I think the salt is actually worse for keeping thing cool longer.

    Most of the cooling capacity of the ice is in phase change from solid to liquid. The salt is moving it to -10 which means bigger gap from outside temperature. So the cold escapes quicker.

    If you use normal water it will climb to 0 faster, but stay there longer.
