Water Boiling Over the Fire

Bottle Boiling

You’re lost in the middle of nowhere. You have a source of water but no suitable container with which to boil it in. You need to purify your water, but how? Here are a couple cool alternative water boiling techniques that actually work!

#1. Plastic Bottle Method:

If you’re in a situation where you have to boil water and don’t have a metal container to boil it in, this is a great option. Since plastic water bottles are common even as litter on the side of many trails, there’s a good chance you might be able to find one on the ground if you don’t have one with you. Simply fill the bottle with water, take the lid of, and suspend it above the fire. It’s crazy, but it does work. It won’t take long to boil, then let it simmer for about 10 minutes if you’re trying to purify it. As long as water is touching the plastic on the inside it won’t melt. Some plastics release chemicals faster when heated, so this method isn’t recommended for regular use unless you need to. Try it out at your next campfire, and have fun!

#2. Heated Rock Method:

Start by finding 10-20 dry stones that will fit in your water vessel. I say dry, because if you choose rocks from a riverbed or wet area, the rocks may have absorbed water, which, when heated could result in an explosion (which you don’t want). Put all the stones in the centre of your fire, and maintain the fire for about 30 minutes with the rocks inside it. After this time, take a couple of sticks to use as tongs, and very carefully take the rocks out of the fire, blow off the ashes, and place in your water. Do this with all your stones, and pretty soon your water should be boiling. KEEP YOUR TOES AND FINGERS AWAY FROM THE ROCKS! These rocks when heated like this can be over 1000 degrees Fahrenheit (about 530 degrees Celsius)! Using this method you can boil water in many different types of containers that can’t be put over a fire, such as wood.  Here’s a great video on how to correctly do the heated rock technique.

Have fun trying out both of these out, but remember to be careful, because you’re dealing with very hot stuff!
