I was looking at the ice pack in my freezer, and noticed it suggested you put it on top of your food in the cooler because “cold travels downward”.

Let’s keep in mind we’re not talking about cold wind, but warm and cold things in direct contact.

Uhm hm. Shouldn’t there be a law that you can’t manufacture and sell something without a clue as to why it works?

  1. Not sure if I missed something in science class… but I assume the principles of convection still apply in the “airspace” in your cooler/lunchbox?

    For a mass-consumer product, I don’t really see what the problem is in simplifying things that far, although I’d be annoyed if, y’know, third graders were taught that.

    • I find it terribly amusing that your standards are higher for third graders than for the general public.

      I’m not saying that’s wrong, mind you, just funny. :)

      Assuming there is any room in said lunchbox for air to circulate.

      Really, I’m just being a smart-ass – I know that it would simply be confusing to write on an icepack that heat travels upward, so you should keep your icepack on top.
