Kind: captions Language: en uh guess who just turned up at my place it is Grant Thompson the king of random what's up guys Grant is actually gonna show me a little survival tip uh let's say you're stuck out in the woods and you need to make a fire but you don't have say matches or a lighter we're going to try to use a Ziploc bag to start a fire I guess when you're Building A Fire the first thing you're going to need is some Tinder so we're going to have to go scou around for some options this stuff works pretty well and this is pretty dry yeah we definitely want something that's off the ground if possible because we need it as dry as possible the first step was to grind up the Tinder in into a fine powder I'm just following Grant's instructions here I'm not really sure if this is going to work see that right there that's the stuff we're going for it's super fine we're going to take our base plate we're going to pinch a nice little pile in there okay so at this point we're pretty much ready to start the ignition process so what do we need for that we're going to need a Ziploc bag and a little bit of water now this is just a regular Ziploc sandwich baggie we're going to pour that in until it's about halfway full you let me know when grab water from a creek or a stream or wherever you like now here's the trick we want to develop this into some kind of a liquid sphere we're going to be making a liquid magnifying glass so I do that by turning my Ziploc bag you know 45° so it creates this diamond shape and then we're just going to gather these two corners together we're going to lose a little bit of water as we do MH and we're going to pinch that off and the next goal is to twist it to trap all that water inside you see as I twisted it creates pressure it exerts almost an equal pressure on all sides and now while it's not a perfect sphere it will eventually start to bubble out into a nice liquid sphere where we need it we've essentially just made a makeshift magnifying glass and you start the fire the same way you would with a magnifying glass now once you roll the ball around you can see where it looks the best we're looking for as close to a s as possible which is right there now if I back it out wow you can see there it starts smoking immediately that's incredible the focal length of a lens is the place where all of the light converges so that's really what we're trying to establish here right is position the Tinder pile at the focal point of this spherical biconvex lens essentially now you can see this has been smoking for a little while M we've developed a little bit of an ember base it's burned a little bit yeah yeah and so now I'm going to sprinkle a little bit more fuel on top there and that will cause the heat to rise and burn that from the bottom and then I'm going to hit it again from the top nice it's interesting how you're like kind of bringing it down so that the surface of that is not actually where the most concentrated rays are you're concentrating even deeper down into the pile that's right because um we don't want the heat to dissipate too much and if we're at an extreme focal point like this the Heat's going to bleed off so if we can warm the surrounding area it actually helps speed the process right we're just going to repeat that process until it will stay smoking on its own we've only been at this for a minute or two and the amount of smoke we're seeing there is uh is pretty significant little bit of sprinkle little bit of sunlight rinse and repeat really elevating the temperature mhm at this point our pile is smoking pretty well on its own now I'm going to go ahead and take this plastic bag and just set it to the side we could reuse this again if we wanted to at this point we can probably start adding smaller pieces of Tinder mhm you'll get a few of these little pieces here we're going to build that into a small we want it to be extremely light Airy sure to still allow the oxygen to get in there exactly cuz if you take away the oxygen you smother the fire cool I think right there we're just going to let it sit for a couple minutes now while that's going we can start chopping up some of these pieces we just found lying on the ground they're dry it's almost like straw we're going to pull them into very thin fibers we want to make something that resembles a bird's nest something that's light Airy and can catch fire very quickly and now we need to transfer this without disturbing the coals as much as possible the way that I like to do that is take this base we're going to take this grass we're going to put over top and we're just going to gently roll it over like this oh wow now you can see all those hot coals transferred down into the grass and we're just going to cover it over to help conceal block it from some of the wind like this and now because of all that straw the air can flow through it and help build the heat one trick that I use that looks a little bit funny I just stick this in my hand and spin in circles and it really works honestly that's impressive you can already see it smoking a little bit more we're going to give that a second just for the heat to build back up yeah but you can totally see there's a lot more fuel catching on fire now what we want to be seeing is thicker smoke and we want to see it progressing if we see the smoke dying down or getting weaker like slow down get it out of the breeze give a chance for the Heat to build this is ready if you look down in there you can almost see glowing red Embers now it it wants to light it wants to light it just needs a little bit of a flick just going to build up a little bit more little spinning trick oh you see that just caught flame there go boom and then we put down here oh that didn't work shoot sorry Derek it's okay we've clearly demonstrated forming fire well that my friend is how to start a fire with a sandwich bag and a bright sunny day that's nicely done I want to say a huge thank you to Grant here King of Random you should go check out his channel does lots of very random things and has taught me a thing or two that's for sure a lot about survival hacks and a lot of those things that you really shouldn't try at home and we show you why you shouldn't try them at home in fact we just put a video on my channel trying to melt glass we took a Dr Pepper bottle and melted that in the backyard and it worked amazingly well so go check it out I'll put a link in the description
