 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is the floating plate experiment. Atmospheric pressure at work. As always, adult supervision is required. What you need for this experiment is a plate, matches, tissue, glasses, and some water. To set up this experiment, take some regular tissue. I take three pieces of tissue and stack them right on top of each other just like this. There are two. When we get the third one there, we're going to fold that up into a square. Fold it in half and fold it over one more time. That's where we're going to want to be like that. I'm going to fold it over one more time just to get it wet. Soak it in the water so all the tissue gets wet. Then lightly squeeze it out so you get excess water out so it's just damp. Then you're going to unfold it one more time back out so it's that square again where it's a rectangle right now. Pull it out to a square and put it on a plate and pat it down so it stays right on the plate right there. There you're going to need adult supervision as we need five wooden matches. We're going to place four of them down towards the center of the tissue, laying them exactly on top of each other just like this. You're going to want to pre-make sure you have a glass that already can fit over the end of all the wood so when we place it on very quickly. I've already done that. The glass is on the left. Then you're going to take your fifth match, put it down on top of it, let it light. Just go ahead and put the match down right so it's on top. Wait until it ignites and then put the glass over it immediately like that. Boom, it's done. That's what you need to do. Here we go. Go ahead and grab the glass and pick it up. You've got your floating plate and glass right there, nothing underneath it. You can turn it sideways. It's got a completely air pressure. What happened here is when we lit the match and we put the glass over it very quickly, the match burned all the oxygen inside, lowering the pressure on the inside. Therefore, the air pressure pulled it down and created a section holding the plate down. Now we're going to see how strong the section can be in this glass. We're going to give it a test and we're going to try pouring a couple glasses of water and see if it can pick it up. See here, there's a little bit of liquid from the tissue that pulled up as it got sucked in with the low pressure. I'm going to fill up a couple glasses of water. They're about eight ounces and so it can be any size. We're going to try to even these out so we have equal weight. I'll fill both of these up so they're just about right. That's a little bit off, but it's good enough. Put them on each side and have a test to see how strong the lower air pressure in the middle and the vacuum is by picking it up. We've got about 16 ounces of water with the glasses and it goes up. It's pretty strong. We're set. That was a good test. We're about 16 ounces. We decided to go a little bit bigger here in our test. These bottles are 16.9 ounces, so five of those will make approximately about 84 ounces of weight. We're going to see if we can pick those up without the section breaking and the plate breaking and me getting in trouble. A little drum roll. It did it, 84 ounces. I'm not going to push my luck and try any more. That's pretty cool. I hope you enjoyed this video. Remember to share and like and thanks for watching. Hello? About kids friends at? Yeah, we have videos. Right over here and those videos over here. Okay fine, hang up.
