Stay away from large groups and unorganized mobs. The potential for disaster is much greater in a mobmentality. Everyone is acting on instinct instead of rational thought. In the event of a global catastrophe,drinking water may become very hard to find. I’m going to show you how to make a water filter at the things which you can find lying around.
Alright. I’m going to show you how to make a water filter for absolutely free and it’s a good water filter too. I think you will be amazed.
好吧！讓我示範如何製造一絕對免費的濾水器。這個濾水器挺不錯的，我想你會感到驚喜。 First of all, we have a bottle. I’m using a 1-litre bottle here for demonstration. But you're gonna use a 2 or 3-litre bottle, or a plastic milk jug or a big Hi-C container, Something larger.
This is just for demonstration I have. It’s already cut off the bottom. I cut a little notches in this part so that the lid goes on in here.
這瓶子只是用作示範而已，我已把它的底部割開。 我在這裡割了些小缺口，好讓蓋子能夠蓋上。
OK, I get a rock. OK, I have some small pebbles. I have some medium-sized rocks. You've got sand. And we've got charcoal that are already pretty broken up into little BB sized pieces
And I'll tell you how to do that as I'm demonstrating the filter. So first thing we're gonna do, is we're going to, Pick that up off the filler. And take this. Take a rock and put that down there like that as the blocker to keep everything from falling through. We're gonna take our middle-sized rocks here. And we're gonna put a bunch of this medium-sized rocks and then like that.
OK? Then the next thing we're gonna do, We’re going to take a bunch of our pebble-sized rocks. We’re going to put them down, as such. You know there's a couple that'll drop out, but what will happen is that will eventually totally stop.
行嗎？之後，就是取一堆卵石般大的石塊，把它們放進去，像這樣。有一些會掉出來，但總會停下來。
OK. So now we have that like that. What we’re gonna do, we are going to take our charcoal and we are gonna put that down in there like that. OK. Tap it down a little bit. Push it down in there until it’s nice and tight. Nice and packed in there.
Then we’re gonna want to take just one of these smaller rocks. Just put a thin layer on top of here, like that. This is where your sand comes in. Sand always goes from the top. Put your sand in there, as such. You want to leave a little space on top of here for pouring your water into.
Now, like I said, you’re gonna want to use a 2 or 3-litre bottle to do this because you’ll be able to filter more water and get the water much cleaner. This is just a quick demonstration to show you how well these filters work.
So we have the rock, some medium-sized rocks, small little pebbles, layer of charcoal, a little layer ofsmaller rocks and then sand on the top of that, as you can see here. And that’s basically the construction ofthe water filter. Right there.
OK.Now for the cool part of the demonstration. I have already run a glass of water through here to rinse the dust of the charcoal. There’s always gonna be dust on it. You’re gonna want to run a glass to it if you’re using a 2 or 3-litre bottle. You’re gonna want to run a couple of glasses of water to, until you see the water come out clear. Then you’ll know you’ve rinsed all the carbon dust out of there.
But anyway, you can see this water. Very nasty, stagnant, floaters on the top. Pretty nasty stuff. You wouldn’t drink that in a million years. But once you put it through here, it’s going to be a lot better.
