    Is spring time again, with new seasons, new mood…

    It is time to change the wallpaper again.

    Oh, no. Not again…!!! You kids gonna shout.

    Ok, ok, I know getting the wallpaper of the wall in pretty much hard work.

    But, you want your new Spiderman, Batman, X-Men or even Star Wars wallpaper or what?

    So, no pain no gain. But, this time we gonna make less pain.

    Heres my secret, grab a pail, put equal amout of water and liquid fabric softener (if you don’t know what is this go ask your mum). Then. mix them nicely. You might need a lot of this solution for a whole room.

    Now, got grab a paint brush. 😉 Is fun time !!!

    Brush the wallpaper with the water and softener solution!!! Kids, keep brushing until the old wallpaper is really wet.

    Yeah, this Cool Experiments For Kids.

    Once you done with it. Go watch a cartoon or leave the painted wall for 30 minutes or so for the solution to soak into the wallpaper.

    The wallpaper can be peel off with less effort now.

    Explanations:-
    Even with help of the softener removing the wallpaper is not an easy task. But, soaking the wallpaper with the water and softener solution make the wall more smooth and lubricate. Thus, helps in getting the wallpaper down. As you all know, the wallpaper is glue to wall using heavy duty glue and you still need some effort to peel it of the wall.

    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.

    I will pressume everyone of you have taken a bus. If you have not ride on a bus before, go out there and enjoy!

    So what happen when a motionless bus started to move forward, you move backwords.

    When a stop suddenly, you move forwards.

    This is exspecially true when you are standing on the bus. If you wanna relive experience this, ask adults to accompany you to take a bus ride.

    You will be asking me what is all this bus thing got to do with Inertia.

    Ok. All object in the world (car, bike, bus, pens, you, your friend and many more) will continue moving (in motion) unless something stops them.

    Again, all object is the world will continue stopping (not moving) unless something moves them.

    But, objects being objects (verbs) will refuse/resist/object to start moving or stopping. The bahavior of the objects are known as Inertia.

    That’s is why Newton’s first law of motion a.k.a Law of Inertia states:-

    An object tends to stay at rest and a moving object tends to continue moving with same speed and in same direction unless being acted by an external force(this is the something I mentioned just now).

    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.
