Science 08 : Friction Power

Do you believe that friction is one of the science with amazing experiments ever? Then, let's know friction first. Friction is one of the contact force type in physics. Without friction in this world, everything will be slippery instantly and no more sports(except for water sports). So one of the awesome experiments on friction power is the 2 phone book that each pages were stacked together. once you do that completely, you can't separating the 2 phone book. Even, with that much power you can lift up a car with the phone book stacked together. Believe me or not, it's a cool science of friction.

Science 07 : Water

Everyone knows this, right? Water is one of an important source of life in the world. 70% of human body is actually water. You can't survive without drinking water everyday, and lessing drinking water could make some problems for you, like dehydration or even death(not drinking water for more than 2 days). Top of mountain have clean and cold water. It is also as a water source. Not every mountain, some contains hot brimstone contained sulfur and stay at the water for a short time is healthy. If you long time in the sulfur water, you will pass out. Water in chemistry writed as H2O, a compound between 2 elements; 1 Hydrogen and 2 Oxygen. Water is also an universal solvent. But now, most of the water in the world now are polluted. Polluted water could bring diseases, even cancer or death. The worst history of water pollution is in Minamata bay, Japan. A factory dispose a dangerous waste known as Mercury. It kills thousands of people. Not only mercury can polluting water, there is also radioactive waste, iron, Fluoride, black tin, nitrate, garbage, and anything else. Also, the stock of clean water is decreased because the forests and trees are decreased. Why? Trees could store waters. Sun's heat make the water from trees evaporating (called Transpiration) and condensation happen in the sky and forming a cloud. The cloud getting heavier and then raining is happening. So, what happen if there is no trees? The answer is like a Sahara dessert and like Atacama dessert. Atacama is known as the driest place in the world because rain is rarely happen. So, do you want your place hot like desserts? If you don't want, plant some trees and don't waste water and polluting water. Because..."WATER IS ONE OF OUR IMPORTANT SOURCE OF LIFE"

Science 06 : Acids and Alkalies

Did you know soda drinks, right? Now, have you ever wonder why don't drink too much? Then, let's know about acids and alkalies. In a Ph (Power of Hydrogen) meter instrument as known as Litmus Paper, you will find that a soda drink has a medium acids. The Ph of soda drinks are 2,8. For stomach acid, the Ph is 2. Now, what is Ph meter? How does it work?Ph (or Power of Hydrogen ) metering instrument is a Litmus paper. To test an object is acids or alkalies, make the object to liquid and put 2 Litmus paper (one blue, and one red) into the liquid. If the litmus paper didn't turn into other color(red/blue), it means the Ph is 7 or Neutral. If it's lower than 7, it means acids. 

Acids are sour(sometimes), and can be corrosive if they are strong, even can "eat up" metals and flesh. There are 4 types of acids :

1. Strong acids : 0-2.
2. Medium acids : 3
3. Weak acids : 4-5
4. Very weak acids : 6-6,9.

To neutralize acids, use alkalies. Alkalies is an opposite of acids. Alkalies in Ph meter is higher than 7. Alkalies are bitter, and can be corrosive too if they are strong, even could burn skin. There are 4 types of alkalies :

1. Very weak alkalies : 7,1-8
2. Weak alkalies : 9-10
3. Medium alkalies : 11
4. Strong alkalies : 12-14

Science 05 : Which Enviroment Situation That Can Broke Your Glue At You Shoes Quickly?

Have you ever try to play soccer with your favorite soccer shoes? If you ever try, have you ever try in 3 different situation? Well, try in this 3 situation of the field : Dry ,Raining ,and Seawater 3 Cm  flood. But don't be suprised, seawater is the answer. It broke down glues quickly and your shoes are broken. A normal water could do the same as the seawater, but it'll need more longer time than using seawater. So, I said now to you : Don't used shoes when you are near the sea or playing rains with your shoes, especially if that shoes are very important to you.

Science 04 : Safe Simple Electric Light

Some person maybe afraid of dark when they going to sleep, so they buy night lamps. Some person maybe already start to think "Hmm, I think I better make it by myself. But how?". If they're gonna ask that, I'll answer it. But first, you need to learn electricity flows. All thought, you should read books to know about this better. But now, I'll help you to make one. First, you need this things on the lists :

1. Mini light bulbs for experiments(note: the light bulbs must able to light by batteries power)
2. Batteries Holder ( 4 Batteries holder )
3. 4 Batteries size AA
4. A medium size box ( Don't use big boxes, you'll need more batteries & light bulbs for that )
5. A tracing transparent paper (I mean the paper you'll able to trace something manually by your hands)
6. Cables
7. Light swich
8. A Pencil
9. An eraser
10. A Ruler ( at least 30 cm )
11. A Glue
12. Decorative materials
13. Scissor / Cutter ( I recommend to use scissor )

How to make it :

1. Draw any picture you like in the transparent tracing paper. Note: you can decorate the picture too by using color pencils or markers, even you can use a dust glitter.
2. Cut a hole shaped rectangular in the box, but make it like a frame.
3. Now, rearrange the light bulbs with the cables and the light switch. Then, attach it to the box. Make it see-able by the hole.
4. Attach the picture you draw in the transparent tracing paper using a glue in the box, right in front of the hole.
5. Decorate the box using any decorative materials you want
6. Now you get your own night light in box shaped.

If you are creative enough, you could turn it into any shape you like or if you want to have a Christmas type lights, you can use a color changing lights and no box used. So just simply used a color changing lights and connect it to the cable and the battery holder and the light switch. I guess that's all I've got in here. Well, thank you for reading this until the end of pages.

Science 03 : Homemade Cold Mist + Extra

Hmm... seems interesting to feel a cold mist, especially you made it by yourself. So, to make the Homemade Cold Mist, you will need :

1. A big wide transparent bowl
2. Some Dry Ices
3. Water
4. Something to grab the Dry Ices
5. *Soap(note: it doesn't important, except if you want to make soe bubbles)

How to make it :

1. Prepared some water in the transparent bowl
2. Using any instrument, grab a dry ice. Bigger the ice, the long the mists. (note: don't touch dry ices using hands, DANGEROUS!!!)
3. Put the dry ice into the water in the bowl
4. You have a Homemade mists.

Now, if you already try to make it and you think it's boring, then here some my advice to make it more interesting:

• You can add some soap. It'll make bubbles for you
• Add some lights that able to change colour below the bowl, then turn off the light. I recommend to not used any soap.
• Add some food colour. Note: you can combined it with colour changing lights like in the 2nd recommendation.

That's all for the Homemade Cold mists. If you want to try, careful for the dry ices. Good luck for trying this at home.

Science 02 : What Shouldn't You Do When In A Gas Station?

This time, we are going to discuss about gas station. In every gas station, there will be a warning : "Do Not Used Cellphones While In Gas Station". Is that really true? Well, it's already tested by pouring a petrol ( or some kind of thing ) in a caravan with a cellphone inside it. When from outside, a person rings the cellphone. It isn't working, even witm many cellphones. But instead, they try to used a wire and a person with nilon clothes. The person with the nilon clothes asked to make electric statics then touch the wire. Actually, It did! Why? Electricity sparks a fire. Petrol ( Or some kind of thing ) will burst up if there is a fire. So next time, don't used a nilon clothes when you are in a gas station, or you will toast.

Science 01 : Backfliping

If you try to do some backflip, I don't think you can do it instantly. Only experts can do that. But, there is a science behind a perfect backfliping. First, you need to jump in the air. In the air, you need to bend your knees. It will accelerated the speed of the rotation. Then, land it perfectly with standing legs. If it fails to stand, you will fall. Now don't you dare to try yoursself backfliping without help from experts, or you'll get injured or even worse.
