Water Rocket!

Ever tried making your own rocket fueled by water? Well, that's what we did this time around. We made water rockets! All you need is a plastic bottle, a cork with a hole through it in the middle and a bicycle pump. Technically any pump will do the trick if it's able to pump air.
Follow the steps below and you should be able to build your very own water rocket.

1. Fill about half of the plastic bottle with water.
2. Cover the top part of the bottle which is open with a cork.
3. Fix the air valve of the bicycle pump into the hole in the cork.
4. Invert the bottle and have someone beside you to hold the bottle.
5. Make sure there is no water leaking out of the bottle and the flat part of the bottle has to be facing upwards.
6. Slowly pump air into the bottle. When pressure is too great for the bottle to handle, the bottle thrusts itself forward causing it to lift high in the air like a rocket.

Thus, you've made your very own water rocket!

Computer simulation of how a water rocket works.

Water rockets are cool. Below are pictures of water rockets made by the members.

Carefully holding the inverted plastic bottle.

"It's gonna lift anytime........

........and launches into the air spectacularly!"

Without delay, they make another water rocket.

Same outcome though. Up up high in the air!

They didn't stop. They continued making water rockets for an hour straight.

End of the day, everyone had a jolly wet time.

Math Humor!

This post includes a few mathematically humorous jokes and sayings that any mathematician can appreciate! The jokes contain something essential about mathematics and the mathematical way of thinking.

 Enjoy!

Q: What did zero say to eight?
A: Nice belt!!


Q: What do you call a mathematician's bird that won't eat?
                            A: A poly "no meal"


Q: How does one insult a mathematician?
A: You say: "Your brain is smaller than any ε > 0"


Q: Why do you rarely find mathematicians spending time at the beach?
A: Because they have sine and cosine to get a tan and don't need the sun!


Q: How do mathematicians induce good behavior in their children?
A: 'If I've told you n times, I've told you n+1 times...'


In some alley, a function meets up with a differential operator:
"Get out of my way - or I'll differentiate you till you're zero!"
"Try it - I'm ex..."
"Too bad... I'm d/dy."


Top ten excuses for not doing homework:
I accidentally divided by zero and my paper burst into flames.
It was Isaac Newton's birthday.
I could only get arbitrarily close to my textbook. I couldn't actually reach it.
I have the proof, but there isn't room to write it in this margin.
I was watching the World Series and got tied up trying to prove that it converged.
I have a solar powered calculator and it was cloudy.
I locked the paper in my trunk but a four-dimensional dog got in and ate it.
I couldn't figure out whether I am the square root of negative one or i is the square root of negative one.
I took time out to snack on a doughnut and a cup of coffee. I spent the rest of the night trying to figure which one to dunk.


Salary Theorem: The less you know, the more you make.
Fact #1: Knowledge is Power
Fact #2: Time is Money
We know that: Power = Work / Time
And since Knowledge = Power and Time = Money
It is therefore true that Knowledge = Work / Money
Solving for Money, we get:
Money = Work / Knowledge
Thus, as Knowledge approaches zero, Money approaches infinity, regardless of the amount of Work done


Q: How many mathematicians does it take to screw in a light bulb?
A1: None. It's left to the reader as an exercise.
A2: None. A mathematician can't screw in a light bulb, but he can easily prove the work can be done.
A3: One. He gives it to four programmers, thereby reducing the problem to the already solved
A4: The answer is intuitively obvious


Q: Why do they never serve beer at a math party?
A: Because you can't drink and derive...

A physicist thinks reality is an approximation to his equations.
A mathematician doesn't care.


Did you hear about the teacher who was arrested trying to board an airplane with a compass, a protractor and a calculator?

He was charged with carrying weapons of math instruction.


Pick up lines:
1. Honey, you're sweeter than 3.14
2. I'm not trying to be obtuse, but you're acute girl.
3. You and I would add up better than a Riemann sum.
4. I'll love you from here to infinity
5. You fascinate me more then the Fundamental Theorem of Calculus.
6. Are you a differential function? Because I'd like to be tangent to your curves!
7. I am equivalent to the Empty Set when you aren't with me.

Math Facts!

Facts about the golden ratio, pi, geometry, prime numbers, amazing numbers that are so big it’s hard to even understand them and so much more! Read on and have fun learning about math.


Mathematics is important in many different types of jobs, including engineering, business, science, medicine and more.

It is believed that Ancient Egyptians used complex mathematics such as algebra, arithmetic and geometry as far back as 3000 BC.

It wasn’t until the 16th century that most mathematical symbols were invented. Before this time math equations were written in words, making it very time consuming.

What comes after a million, billion and trillion? Why a quadrillion, quintillion, sextillion, septillion, octillion and nonillion of course.

Cutting a cake into 8 pieces is possible with just 3 slices, can you work out how?

An icosagon is a shape with 20 sides.

A three dimensional parallelogram is called a parallelpiped.

Trigonometry is the study of the relationship between the angles of triangles and their sides.

The smallest ten prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29.

The name of the popular search engine ‘Google’ came from a misspelling of the word ‘googol’, which is a very, very large number (the number one followed by one hundred zeros to be exact).

A ‘googolplex’ is the number 1 followed by a googol zeros, this number is so big that it can’t be written because there isn’t enough room in the universe to fit it in! It would also take a length of time far greater than the age of the universe just to write the numbers.

The number pi (the ratio of the circumference to the diameter of a circle) can’t be expressed as a fraction, this means it is an irrational number. When written as a decimal it never repeats and never ends.
Here is pi written to 50 decimal places: 3.14159265358979323846264338327950288419716939937510

If two quantities have a ratio of approximately 1.618, they are said to be in the golden ratio. This ratio has been used throughout history to design aesthetically pleasing art works such as the Parthenon. It also appears in paintings, music, the design of books, and even in nature.

Amazing Science Facts

Our lungs are known to be the lightest of all organs in the body.

Our Very Own Garden!

Till our third meeting, very few of the members knew we had our very own garden. Frankly speaking, only Pn. Chuah knew from the start we had one. Located behind the school's office beside the boy's toilet just to the left of Block C, there stood our garden.

The club's garden.

Moving on, this week's meeting was entirely to clean up and re-decorate the garden. To help achieve this, Pn. Chuah brought her sister to organize and co-ordinate the place.

Pn. Chuah and her sister.

Pn. Chuah's sister told the members what was the plan and where was the ideal place to put the pots and plants. She then led the clearing up of unwanted plants and with the help of the members, cleared up the whole place.

Pn. Chuah's sister instructing the members the plan.

After receiving instructions, members set out to complete them.

Removing weeds and other unwanted plants was their first task.

After completing their first task, the redecoration of the garden began. Pn. Chuah's sister asked for bricks to properly arrange the sides of the stands which held the plants to prevent the pots from falling. So detailed was Pn. Chuah's sister's vision, it seemed impossible she would not notice any flaws in the garden.

Members assigned to find bricks.

After inspecting the garden, Pn. Chuah's sister then gave the green light to fill the place with flowers. She told members where and what to put in every inch of the place.

Members start filling the place with flowers as Pn. Chuah inspects as well.

After feeling satisfied enough with the garden, Pn. Chuah and her sister then called it a day.

The garden after a good day's job. More plants shall pour in the near future.

Though feeling tired and exhausted, they along with the members felt it was a good day's job. We then thanked Pn. Chuah's sister was helping us out willingly and headed back home after a group shot together.
