Re: Ice chest . . . pour water out?
Some physics facts for the 'cooler minds':
- Keeping ice in the bag will made the ice melt slower because of the lack of air exchange. This means your food will stay warmer, not the desired effect.
- Salt is not magical; It will not keep your cooler colder longer, just cooler than without. Salt will lower the freezing point of the water, which means your food and beverages will be colder, but at the expense of longevity. Fine for a quick few hours out, but bad for an all day event.
- Keeping the water in the cooler indeed does keep the cooler cold longer, as the water will likely be just above freezing (or slightly below with salt) so long as there is still ice floating in it. Cool water makes and keeps items cool just as warm stuff warms a cold cooler.
- Light colored coolers will reflect the sunlight, keeping your cooler cooler. Luckily for us, most 'marine' coolers are white.
Hope that explains some things.
