What the hell is that bubble of air under a frog’s neck???
More specifically, under a male frog’s neck.
That bubble, or so called vocal sac, is used to contain air so that the male frogs can force it through their larynx and create the croaking sound. By keeping their mouth and nostrils shut, they are able to amplify the sound.
Why only males?
Male frogs croak to attract females as their mating call and also to repel away other male competitors form their territory. Females do emit a vocalization for breeding but it’s usually too soft to be heard.
Basically, frogs will try to have sex with anything that looks like their cup of tea. Also, they do not cause warts but some of them do have bumps do contain poison so watch out.
Bat bombs are literally bombs filled with bats. How is that destructive? you might ask. Batman is obviously not the inventor, if you were thinking he is related to this in any form.
It is World War 2, 1942 - 1944. Many Japan homes are made of paper and bamboos, flammable materials. So, of course to defeat them is simply to light them up.
Hence, the bat bomb was created. The "bomb" was actually a casing for containing around 26 compartments, which totaled up to 40 bats. Each bat would carry incendiary devices, specially made for them, that would light up and burst into flames.
TADA this will destroy all of Japan's homes.
But wait. You have to imagine it all out.
Firstly, the bombs will be dropped way up in the sky from around 10 B-24 bombers each carrying about 100 of these bombs, 1000 feet high.
Then, while falling, the bombs will split into the casings, falling apart and landing on the houses or somewhere. The bats will fly out during the dark and look for shelter, especially a dark place. Sneakysneaky.
The timed device will then burst into flames lighting up all the paper houses and also probably the bats :(
And there you have it, the bat bomb. Btw it is real, really. I'm not making all of these up pffft.
It seems eating too much protein and just protein only, will cause death.
A liver can only possibly metabolize 285 - 365 grams of protein a day while kidneys are also limited in removing the poop of protein catabolism, urea. Having too much urea (or ammonia) will cause hyperammonemia, or also brain damage.
Before dying, you might have diarrhea, headache, fatigue, low blood pressure and heart rate. You will also crave for food that have a lot of fat or carbohydrates instead of protein.
There's rabbit in rabbit starvation for a reason. Rabbits are one of those animals that have almost no fat and just purely protein.
And because livers can only metabolise this much protein, not only will u get protein poisoning, you will also starve from the lack of energy it gives.
Hence, you might get starvation just from eating rabbits and thus, the name Rabbit Starvation.
Also, I believe there's rabbit starvation for a reason, there must be a balance in all things. If there was no such thing as protein poisoning, then the world might just be consuming only protein and animals (esp. rabbits) will go extinct even faster!

I was curious about how magnets, pieces of metals that mysteriously repelled and attract each other with invisible forces like magik, were able to just that. Hence, I searched it up and much of the information gave me a headache. HowStuffWorks, however, has nice graphical images that helped me understand a lot. Be sure to visit their website for any visual help!
So to summarise without a headache...(I try...)
Magnets as you know, are objects that creates their own magnetic field. A surrounding area around them that attracts (mainly) metals and attracts/repels other magnets.
Types of Magnetic materials:
Ferromagnetic and Ferrimagnetic materials are those that we can feel its forces of attraction because its strong enough.
Paramagnetic materials are super weak shits that we can't even feel its forces of attraction if it is multiplied a thousand times.
Diamagnetic materials are also weak shits. However, they repel magnets instead of attract them.
Everything is actually a magnet but what makes us call them a magnet are permanent magnets. Permanent magnets is an object made from a ferro or ferrimagnetic material and creates its own persistent magnetic field, whether natural or man-made.
OK, now for the main point.
How do they attract. Let's use our imagination as usual. Think of a hollow magnet that is bar shaped (NOT A BAR MAGNET). Yeah. Imagine there's a lot, A LOT of hyperactive crazy moving dots that goes in at one end of the magnet and out in the other and loops one round and goes back in the magnet again, all in the same direction. So, let's just say the end that dots go in is the "South Pole" of the magnet and the other end is the "North Pole". Now imagine another similar object with those dots...
If magnets were to be placed on the opposite direction, they would attract right?
Normally, the dots rushing out of the North Pole would turn back, however, since there's a South Pole nearer for them to enter, why not? Hence, the magnets are pulled.
I'll leave the repelling on your own. Think about it ;)
We talked about how magnets attract. But why not every object?
The reason is because magnets are actually made of tiny pieces of magnets... WHAT?!?!?!
Yeah... Those tiny magnets can be called as magnetic domains. These things actually contain North-South Poles too and they align to each other to form a magnet. If they were to point in opposite directions, meaning the dots would crash into each other, they would cancel out and thus, no magnetic force is created. Hence, the more "aligned" an object is, the more stronger its forces of attraction.
If you went this deep, you must want to know more. Here goes
Of course, we can go even deeper as to why the mini-magnets attract to form a large one. So why exactly do magnets attract? What are those dots...?
They are actually electrons of the atoms of an object. If you went to school and studied your chemistry, you should know about the drawing of dot diagrams of your electrons. They are mostly in pairs, aren't they? In each pair, both move in a opposite direction and cancels each other out. However, some elements (mainly ferro/ferrimagnetic elements) have one or multiple unpaired electrons. Since they have no opposing pair, they all move in the same direction, creating a tiny force. When combined with other atoms, they create more force and with enough force, they can attract or repel similar objects, depending on their direction.
Since there's mini-magnets in a magnet, just break a magnet and you'll have two!
Striking iron needles with magnets have always been a common and easy way to make a magnet. The reason for this is because those un-aligned mini-magnets will slowly rotate and become aligned.
Where there's a North Pole, there's must be a South Pole. Vice versa!

If one side rejects you, do not worry as the other side will accept~
This will be a simple short post, mainly talking about why domestic ice cubes are cloudy :)
Ice, as you should know, are frozen water aka water in solid form.
And ice cubes, is simply ice shaped in cubes DUH.
If you've ever wondered why the ice cubes you froze in the fridge is always cloudy and never clear...
This is because just like how there's dust everywhere in the air, noticeably under sunlight, there's sediments and particles, dissolved air and minerals in water. Because of spaces in water molecules, tiny stuff like a bunch of air molecules slips in between water molecules easily...
And when water freezes up, it freezes from top to bottom. This causes the particles, air and other molecules to be trapped in the (about-to-be) ice. Once it freezes up as ice, it is no longer a liquid remember? It's in a solid state.
This means that the dissolved (molecules that got mixed inside water) particles and air must appear because in a solid state, the ice only vibrates closely. Hence, the air molecules are forced out of the tightly-packed ice particles, creating the cloudy look.
If you are now wondering why it's not a clear look with bubbles in it, this is because the dissolved gases are very small and they don't have the time or will to merge together to form even a tiny bubble in the ice :]
To read on how to make clear, transparent ice cubes, click on read more!
The same way water evaporates from the open surface, water freezes from the open surface too! It's not necessary from the top. oops.
As water becomes ice, the particles move slower and slower until they form a pattern and vibrate in their position. While gas particles also slow down, they don't stick to each other as they are free.
The more surface area of an ice cube, the more heat it can absorb! Think how you can use that to your advantage ;) (The faster it melts too~)
Something for making it through this waterfall of information…
Clear Ice Cubes!
Because those cloudiness are the result of mostly air particles trapped, one way is to boil the water once or even twice! before freezing it.
Do take note. Putting hot water into your fridge may spoil it!
Another "water" you can use is pure/purified/distilled water.
Are you muscular? What makes a person muscular, strong? And how?
There are 3 main types of muscle in the human body. Skeletal, smooth and cardiac muscles.
In this post, I'm gonna talk about skeletal muscles which is the muscles that you can control aka voluntary
Smooth muscles and cardiac muscles however are involuntary, which means you can't control. They move when they want to. Scary eh? but it is mostly useful. Cardiac muscles is only found in your heart. Get why it's useful now?
So in school, you've learnt that muscles contract and relax yaya blabla and it is made of protein. In fact, it's actually mostly water followed by proteins.
Now, imagine holding a chicken drumstick (yes that's the chicken's thigh), take a bite out of it. See those strips of...muscle? yes, those are the muscles of a chicken's thigh. The only or two reason it's meat is because you're eating it and it's cooked/dead.
Now, look at your arms and imagine those strips of muscle underneath that awesome skin, except... it's all red and bloody and filled with blood vessels and yea.
It's not that simple actually, those strips of muscles are made up of bundles of muscle fibers and those aren't even the smallest yet.
But let's not go so in-depth. What we- (ok actually tbh) What I want to know now is how it grows, how can we efficiently make them bigger and ourselves, stronger?
So, I've found out that
The cross-sectional area of a muscle (rather than volume or length) determines the amount of force it can generate by defining the number of sarcomeres which can operate in parallel.
WTH IS THAT. SARCOMERES. WTH.
To put simply it is something we can't see unless under microscope ok.
It is those inside a muscle fiber. It- ok I haven't even get to using the movement of actin against myosin to create contraction.
From Wiki, we can find this:
A display of "strength" (e.g. lifting a weight) is a result of three factors that overlap: physiological strength (muscle size, cross sectional area, available crossbridging, responses to training), neurological strength (how strong or weak is the signal that tells the muscle to contract), and mechanical strength (muscle's force angle on the lever, moment arm length, joint capabilities).
Now, think about it, what can we improve definitely. Physiological strength isn't it? But then again, how? We all know exercising helps, going to gyms yea, and all the different kinds of exercises that improves all the different parts of our body to make it look "buff". Thing is, how is it making our body produce more of these SARCOMERES.
Muscle growth is called hypertrophy aaand there are 2 types of hypertrophy... sigh.
One is the one mentioned above, making more sarcomeres, Sarcomere hypertrophy. I guessed it right! woot. Another is Sarcoplasmic hypertrophy which is simply the fibers becoming bigger instead of the sarcomeres' increase. It doesn't even matter anyways hahaha because muscle growth uses both.
The main concept right now is:
Stress and damage on muscle invokes hypertrophy.
After you exercise, lactic acid is produced that's why you feel the sour feeling. These lactic acid damages your muscle, but it's not all bad. This allows the body the repair the damaged muscle by fusing muscle fibers together to form new muscle protein strands.
wait. But this only makes your muscles stronger, there isn't production of more muscle.
yes, each fiber has a limit hence to increase strength we can also increase the number of sarcomeres.
Satellite cells, found in muscles with virtually no cytoplasm, are what help to add more nuclei to the muscle cells which in turn creates more muscle cells. This is, sadly, not easily changeable as to activating these cells and the number of these cells differ from person to person. Testosterone, growth hormone, also affects this greatly hence, guys have an easier time growing muscles than girls. Sorry girls!
Just eating crazy amounts of protein without utilizing them is not going to get you muscles anywhere near someone who eats only a meatball a day and utilizes the protein in it.
some "are you f#@king kidding me" "facts" :
The strongest muscle in our body is our tongue, which consists of 8 muscles in total. whuuut.
It takes 17 muscles to smile, 43 to frown. And none to do a pokerface.
The tooth is the only part of the human body that can’t repair itself. nope, you actually can.

Why it always changes, how come some of those numbers go up or down sometimes by a little sometimes so much, why every country has their own exchange rate...
I did, for every single time I saw a licensed money changer, these went through my mind. And we all know the answer to that, before and even after we search it up, is this.
Hence, for ezpz baby learning, let's not think it complicatedly and just use simple terms, my terms. obviously, I would still use the technical terms.
ok let's start by brea
-king it up.
Quite of a common knowledge, exchanging money is just treating $$$ as a product [food, toys, wahever]. You either buy a type of currency or sell it with that guy in the glassbox.
Example, there's that guy in the glassbox saying he buys your local dollar for 2 foreign dollars(say if it's ringgit Malaysia currency). This means that if you gave him a dollar, he will give you twice the amt of ringgit. Essentially, you're selling your local money for the foreign money which in this case is ringgit. Vice versa.
Define BIG and small currency
Adults(or actually anyone) would mention once in a while, wow this "particular" currency is big... or wow this "particular" currency is dominating... okay okay you get the idea.
BUT what do they mean???
To put it simply, it actually just means the currency can be sold for much higher price to other currencies and the more currencies they are sold for a higher price, the "bigger" they are. Small simply means u throw away large amounts for just a few dollars. Confused?
Let's use the previous example. If your local currency is able to sell for 2 ringgit, which is bigger?
... ... ... Ringgit. KIDDING. The local currency.
Don't get confused by my joke, it is local currency.
Why? Because you get more value from what you sold. So, if you sold your local currency and went to Malaysia, in this situation, you could possibly bought more things(value)
I forgot to mention. There's 2 different systems in determining a currency's exchange rate
wow...
this is gonna be a...
looong ride down.
The Floating Exchange Rate
is determined by the market. So, it actually means whatever you're(or every other buyer) willing to pay for that currency, it is the exchange rate. This is affected by supply and demand factors which is like the amt of currency given and taken from the person in the glassbox.
The Pegged Exchange Rate
is determined by nothing. Or rather, it is fixed by the government themselves. It will not fluctuate but the government has to maintain it so it stays stable. Pretty neat but it can cause black markets to appear where people buy at a different rate disregarding the pegged rate.
And then there's the hybrids.
Which is simply both combined together. Most countries uses this system now. So if the floating rate goes crazy, the government will use policies and tax rate to try and calm it down.
Your head must be in pain right now and so is mine. But since this is just ezpz baby learning as we shall not go in-depth with the supply and demand factors that affects the exchange rate, particularly the floating system. I was planning to so I might write about it in the future.
Do click Read more to see what are the supply and demand factors.
FYC (For Your Curiosities) :
Factors that affect exchange rate :
Difference in inflation (Inflation is sustained rise in prices over time)
Difference in interest rates
Trade between a country and the others
Public debts
Terms of Trade (A ratio between export price and import price)
Political stability and Economical performance
Factors affecting SUPPLY AND DEMAND :
Export companies
Foreign investors
Speculators (Investors who make a fortune by selling and buying currencies)
Central Bankers(Local reserves that control the supply of currency in the country)

Watch out! Your current sea might be overflowing with cash!
So there's a hole in your tooth out of the blue and you're like WHAT THE FUCK. or possibly, HOW THE FUCK. And this is how. Yes, those holes are called dental cavities and they are caused by bacteria, mainly Streptococcus mutans and Lactobacilli.
{ These campers stay in your teeth, probably hidden somewhere in between, eating all your sugary shit like glucose, carbs and most of the sweet or awesome stuff you eat and poops out an acid called lactic acid. This friggin acid is the one that causes you to have that hole in your tooth and the black part is the decaying of the tooth with the bacteria. } and this whole "process" is called demineralization.
Of course, where there's de-something, you would expect re-something. AND YES, there is. You must be thinking (if the last thing you want is seeing a dentist) tadaaa hope! N-O-P-E nope.
Remineralization over here is, yes the process which counters demineralization and restores the teeth with minerals commonly fluoride and calcium.
Sooo, technically, if remineralization > demineralization aka beating the hell outta it, there will never be holes in your teeth! Read that again. That is why there is no hope for you if you already have a hole. In your tooth that is.
FYC (For Your Curiosities) :
Acid is the culprit, or you can also say acid is the weapon of the culprit. Hence, even just eating acidic food will cause that hole in your tooth, not just bacteria. So, rinse your sweet tooth with water or gulp that bleach down! seriously, don't. I mean the gulping bleach down part.
Fluoride and calcium may be your tooth heroes but too much of anything is never good.
FIlling is one way, but it stops the healing. (if it is capable to)
