    Yo Kidz, it has been some time i have not written any cool experiments.

    Wanna know why?

    I drank too much root beer. But, that gives me an idea to create a cool experiments.

    Without talking too much, lets get to the materials required:-
    1. A botol of Food colouring (we just need a few drops, red color will do just fine)
    2. A botol of Vinegar
    3. Some baking soda
    4. Dish cleaner or dish detergent, what ever u wanna call it
    5. Water off course ;P
    6. A cup for our experiment
    7. U might need a spoon…

    Hey mom... I need a cup please

    Hey...mom I need a cup please

    A step by step guide for our experiments:-
    1. Ok, I know A & W use glass cup for their root beers. But, due to safety reason I used a plastic cup instead. Remember don’t even drink the root beer in our experiments. Pour water into the cup. U might want to leave some room for your root beer foam.
    Left Some Space For Foam

    Left Some Space For Foam

    2 Put a few drops of the dish detergent liquid
    Add a few drops of dish detergent liquid

    Add a few drops of dish detergent liquid

    3. Since we are making our own root beer. We should add a few drops of food colouring to the water.
    Our Root Beer Is Almost Done!

    Our Root Beer Is Almost Done!

    4. Put 2 table spoon of baking soda into the solution a.k.a our root beer.
    One...Two...

    One...Two...

    5. Open up your botol of vinegar and ready for action. Now, pour in the vinegar and our root beer is done. Watch out, the foam might over flow. If nothing happen don’t cry, no worry. We can fix it. Just use the spoon to stir the baking soda.
    The moment of truth...

    The moment of truth...

    6. Root beer is served ;P
    Root Beer Is Served ;P

    Root Beer Is Served ;P

    Opps...

    Opps...

    Explanations:-

    The foam flowing up the cup was due to the reaction between baking soda (a base) and the vineger (an acid). Once a base and an acid react, it will release carbon dioxide. The reaction of releasing carbon dioxide pushes the foam upwards thus making our root beer foam. The role of dish washer was to create the foam without the dish washer we won’t the foam for our root beer. If we just mix the baking soda (base) and vineger (acid), we will witness something like when we pour a can of Coke into a cup with some sizzzzzzzzz sound.

    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
    4. Water
    5. Spoon
    6. A pair of scissors
    7. You…(to enjoy all the fun) 😉

    Opps...forget the scissors

    Opps...forget the scissors

    Instructions:-
    1.Cut open your cornstarch. Pour the cornstarch into a cup. Fill the cup full.

    Fill the cup with cornstarch

    Fill the cup with cornstarch

    2. Put all the cornstarch into a bowl or container. Use the spoon to stir the cornstarch. How does it feels ?

    Pour the cup of cornstarch into a bowl

    Pour the cup of cornstarch into a bowl

    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.

    You don't need much water

    You 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.
    Cool...It just stay right there

    Cool...It just stay right there

    Yeah...Give me a five!!!

    Yeah...Give me a five!!!

    8. Hold your pet steady on your palm. No touching please!!! See what happen?

    It looks like liquid

    Cool Down...Don't touch it...

    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.

    What,…!!! How can raisin float?

    No worries,  in this next cool science experiments we gonna make the raisins float.

    Hmm…lets prepare all the materials listed below:-

    1. A pack of Raisin off course.

    2. A glass

    3. A bottle of soda water, best if you can get those without colour. A Sprite maybe ;P

    Instructions:-

    1. Fill your glass up with soda water.

    Fill the glass up with soda

    Fill the glass up with soda

    2. Put some raisin into the glass. What happen to the rasin?

    Put your raisins into the soda

    Put your raisins into the soda

    3. Wait for a while…

    Gas Power!!!

    Gas Power!!!

    4. Magic…!!!

    Look! Rasins are floating!

    Look! Raisins are floating!

    Exlanations:-

    Well, as you know kids. Soda water is make up of water and gas (carbon dioxide). So, when the raisins are in the bottom of the glass, gas bubbles started to attach on the surface of the rasins. Once enough gas bubbles are attached on them, the raisins will be floated by the gas bubble. But, once raisins floated on the surface of soda water, the gases are release into the air, thus making the raisins sink again.
