Solid vs Liquid9April 3rd, 2009Chemistry
You must be wondering, how can soild matter fight with liquid matter?
Well, in this cool science experiment we ain’t fighting solid and liquid. But, we are going to turn a solid into liquid. Liquid backs to solid. Sounds like magic…? Looks like magic…But it is not magic…It is Cool Science Experiments For Kids!!!
Let’s get started, you guys just can’t wait anymore.
First, get the following material ready:-
1. A packet of corn starch
2. Some bowls or container
2. A few Cups
6. A pair of scissors
7. You…(to enjoy all the fun)
Instructions:- 1.Cut open your cornstarch. Pour the cornstarch into a cup. Fill the cup full. 2. Put all the cornstarch into a bowl or container. Use the spoon to stir the cornstarch. How does it feels ? 3. Put in half cup of water slowly into the blow. Do not pour the water all at once. Slowly. You actually don’t need much water. 4. Stir the mixture. How do you feel ? 5. Keep stirring until you get a pancake like batter. Now, poke it with your finger. Does it feel like building sand castle ? 6. Now, lets get dirty!!! Hold it in your hand. Squeez it, shape it, move it. How does it feels like? 7. Keep playing with your ‘new pet’ on your palm. Turn over your palm or even give me a five. Let’s see what will happen. 8. Hold your pet steady on your palm. No touching please!!! See what happen? Explanations:- In school, we learn about three states of matter:- solid, liquid and gas. Today, we gonna learn a new thing called suspension. The mixture of water and cornstarch created a suspension. It can behave a like a solid when you poke it, squeez it, shape it, moving it around. That is why the moment you start to stir with water, you need extra energy to stir it. Reason being a suspension will in ‘defensive mode’ when you are touching it, which means the molecules or particles line up to behave like a solid. When you left the suspension alone, its molecules or particles relax, thus it looks like liquid. The moment you touch it, it will act like a solid.

This is a great post, Thanks!
You are welcome
lol one or two of the reviews bloggers write crack me up, time after time i question if they actually read the documents and items before writing a comment or whether or not they only just look at the post title and type the initial thought that comes to mind. nevertheless, it is actually nice to browse smart commentary every now and then instead of the very same, old post vomit which i invariably discover on the internet

i am more often than not wandering across the net just about all of the afternoon which means I usually tend to browse a good deal, which isnt typically a good factor as most of the internet resources I find are composed of pointless garbage copied from several other websites a trillion times, nevertheless I have to give you credit this site is really readable and boasts some genuine material, for that reason thank you for smashing the fad of just simply copying other folks’ blogs, in case you ever want to try a few hands of facebook poker with me just let me know - you have my email address
lol a number of the observations individuals post are such stoner remarks, frequently i think about if they even read the subject matter and threads before writing a comment or whether or not they just skim the title of the blog post and jot down the first idea that pops into their brain. nevertheless, it’s relaxing to browse through sensible commentary from time to time as opposed to the same, old oppinion vomit which i mostly observe on the web i’m going to play a couple of rounds of zynga poker regards
Keep ‘em coming… you all do such a great job at such Concepts… can’t tell you how much I, for one appreciate all you do!
