- Is this advice correct? Are they alluding to Freezing Point Depression? Adding salt to tap water lowers the Crystalloid's freezing point.
Pour 3 tbsp (51 g) of salt into each of your 3 plastic water bottles. Use disposable plastic bottles for the easiest set-up and clean up. Pour 3 tablespoons (51 g) of table salt per bottle. Put the caps back on and shake the bottles to thoroughly mix the salt.
- I live in a studio flat. I know of the Law of Thermodynamics, also here – but my plan is different. Where I live, night time is way cooler than day time. I'll freeze the bottles over night, because even if my freezer heats up more than usual, my night room temperature will still be cool enough. During day time when it's hot, I'll place the frozen bottles in front of my fan to air condition my studio flat. Does this work? I read Quora.
