Who knew you could use a plastic water bottle to boil water in a pit full of burning hot coals?
Most people would expect the plastic bottle to melt but the amazing science behind it is the water actually takes the heat out of the plastic so it doesn’t melt. Allowing the water to successfully boil.
What you need:
- 1 Water bottle with water in it.
- 1 Fire-pit with (only) red hot coals.
Obviously, it’s not recommended that you go into your backyard and boil some water in a plastic bottle just to drink it. The plastic will release bad chemicals into the water. However, when you’re in a life or death situation and you desperately need the cleanest water available, this could be your best option.
