Start a Fire With a Water Bottle

Start a Fire With a Water Bottle

Normally, we’d think of using water to put
out a fire, but in this video, you’ll learn how to use water water to start them. If you’re ever lost in a survival situation,
here’s a little trick you’re gonna be so glad to know. To practice this technique we’ll
use 3 sheets of paper, and a water bottle. A paper with black ink is easy to practice
with, so let’s get started making this top sheet into a platform by folding it in half
3 different ways. The black ink is showing, and that’s a good thing, so now we can prepare
these other 2 sheets by cutting or ripping them in half. This gives us 4 pieces, and
we can fold each of them in half so that they’re creased down the middle. Alright, time for
the action. We’ll need to remove the label from this little bottle and use the convex
edge as a makeshift magnifying glass to focus the sunlight. It only takes a few seconds
to get this paper smoking, and pretty soon we’ve got it smoldering. When the hole is
about the size of a quarter, we’ll need to slowly add multiple layers of papers. Swinging
it around gently will help the air get to the embers, and when they get hot enough .. a
flame appears! That’s it in a nutshell, but in practice you’ll probably find that it’s
not quite as easy as it looks. So here are a few tips and tricks to help you master your
technique . First of all, use a bottle with clear plastic and remove the label. The top
should be smooth and rounded so that it magnifies the image on the other side. I’ve been successful
with colored bottles like this green 2 liter and this little blue 8oz bottle, but the color
absorbs some of the suns energy and makes it a lot more difficult to get a coal. The
color of the liquid also needs to be as clear as possible, but in desperate situations,
it is possible to light a fire with your pee. Look for how to do that in a different project.
If you’re using paper for tinder, use something with big black letters or pictures, or rub
some dirt on it because the black absorbs the heat. Trying to do this on a white piece
of paper is just going to frustrate you. When focusing the light, hold the bottle close
to the paper and slowly back it away, shifting the bottle around to find the area where the
majority of light is concentrated. It should be very bright, and start smoking within a
few seconds. Keep the light focused until a hole begins to burn, and grows to the size
of a quarter. At this point, you can gently set the embers in the creased part of another
paper, and hold it loosely at the corner. Tight enough so that the embers are in contact,
but loose enough to allow plenty of air to flow. When the embers have burned a hole through
the sheet, add another one in the same way, pinching the corner and holding loosely. As
the heat builds, and the process is repeated 2 more times, you should have a billowing
bundle of smoke. It’s at this point you can blow forcefully into the embers, and voila
.. a healthy flame. This is a technique that I’ve had the most success with. It should
work for you, but might take a little practice. If you try this at home, you may be surprised
to learn that you can rub the ashes into your lawn. The potassium, phosphorus and calcium
in the ashes make great lawn fertilizer, so long as it’s in small quantities. For another
challenge, try this with water and a plastic sandwich bag. I found those can work as well!

  1. This is a great video!!! I have just subscribed to you!!! Keep the marvelous work up!!!

  2. I guess today's kids are trying to achieve this with their magnifying smartphone app.
    That said, I tried it with dozens of different glas lenses, when I was a child, but it never worked.

  3. omg this is so cool my seven year old sister told me about this.
    edit: don't judge me my sister is a really smart girl. she's adorbs too! โคโคโค

  4. those saying carrying black ink paper is inconvenient, just have a sharpie. black sharpie ink on paper works

  5. Why you donโ€™t leave water bottle on car seat on hot day. Car was burned to ground here in Australia due to bottle left in cab.

  6. Why so much hassle? Here's a much easier method:
    1. Empty the water bottle
    2. Fill the bottle with gasoline
    3. Pour the gasoline on the firewood and light it.

  7. We were out camping last week so I thought I would give this a shot . . .
    I tried all night but couldn't get it to work

  8. I got the plastic bag one! But I'm struggling with keeping the fire going. How hard do you swing the paper stack? And do you do it the whole time or just at the end when you have a big stack of papers already?

  9. Whoa Well king of random just pissed in front of me. king buddy at least buy me dinner first lol jk cool video man

  10. I'm using a plastic coke bottle and a pretty dark paper however I can only warm up the paper but I don't see any smoke or flames, any tips?

  11. So a discarded water bottle with some water in it could unknowingly start a forest fire. Lesson: don't make litter in fire prone areas!

  12. Gosh…amazing..I spent years on the land and six years off the grid…never came across something like this..thanks for sharing
