On a deserted island you're completely surrounded by ocean water but you can't drink any of it because it's too salty. If you ever ran out of water you'd want to know how to churn salty water from the ocean and your fresh water that you can drink. Well today we're going to show you how using this solar still. The idea was sent to us by many of Los Angeles California. A still something that distills purifies water it does that by evaporating it which means turning into gas and condensing it which means turning it back into a liquid. When the water evaporates it doesn't bring things like Saul and dirt with it. So that's why you get fresh water and are still as part of the sun so it's called a solar still. The salt waters are on the outside and the fresh ones on the middle in the glass. Here's how to make your own. OK so we're not near any ocean so one has to make her own salt water to test this out. One two three five so it's a lot. It's OK now you want to start turning cloudy and lightish now. Right now you just want to pour some of your salt water into

a large pool so that you know nice and slow. Tell you when to stop. OK you don't want too much of it. Because you have to put glass in the glass must be taller than the actual salt water. OK that's good. Yes. Could I take a glass. And place in the center of the bowl. Like I said the glass should be higher than the salt water. Bush should be short of the top of a book like this. Right now you want to cover your bold from plastic wrap and you may even want to take it to make sure the SEALs take off because you don't want any are getting in. OK so the next step is to take a heavyweight like this rock and place it in the center of the plastic wrap on top of the glass so now that your still is done you just need to leave it out in the sun for a few hours. Even entire dead. The longer you leave it out the more water to collect. We have one that's been out for four hours and here's what happened. Rays from the sun heated up the water in the bowl when the water got warm it evaporated and became a gas when the gas rose and the plastic wrap. It turns back into water droplets. Eventually gravity made the water jump

which rolled in the pasta ground towards the rock. Then the water droplets slid off the positive rock and into the glass. So if you want to taste the water and see if it actually worked. Yeah I think so I just wish these goals were a little warmer. That's because it's been outside all before our is really work and what you can see almost is gone. All piled down at the bottom of the little leaves. Yeah it does look like sand. OK so sick after a while. If you are. One chair. OK so we have two cups to see. What's up fresh waters inside they have the glass that was empty and now it's full of fresh water. It's nice and warm it was on the new year. OK. Pretty notable books not salty or funny though. Everyone says not even associate all the eclipse much water getting wired this way is called distillation. It does take a long time so it's not the way most

wired. Fact plate does work. Distillation is a good way to get fresh water they probably have a salt water and a few materials but if you're on a deserted island in a lifeboat in fact lots of lifeboats have solar cells as part of the survival gear do you think a social worker for other like me.
