[intro]

Cats are masterful predators, capable of spotting prey from meters away in the dead of night.

But place a treat in front of them, and they're basically blind.

What's up with that?

How can such good hunters be so lousy at seeing what's right in front of them?

It turns out that their vision isn't always amazing, since being able so see well at night

comes with some drawbacks.

Cats are crepuscular, which means they're most active at dawn and dusk.

As a result, their eyes have evolved to see best when the light is low.

For one thing, their eyes are huge.

They're nearly as large as human eyes, even though their heads are less than half the

size of ours.

Their slit-shaped pupils also have a greater range of size.

Human pupils can dilate to 15 times their smallest size; cats' pupils can dilate by

135-fold,

and get even wider than human pupils to let in a lot more light.

The parts of their eyes that let in and focus light

—their corneas and lenses—

are also proportionally larger,

which ultimately means more light reaches the light-sensing tissue in the back, called

the retina.

And they have an extra reflective layer behind their retina called the tapetum lucidum

, which reflects back any light that reaches it,

giving the retina a second chance to catch what it's missed.

Special cells in the retina called photoreceptors are what actually sense light.

And like us, cats have two types of photoreceptors: rods and cones.

Rods work best in low light but don't sense color very well.

Cones are used in color vision, but they only really work if there's a good amount of

light.

Cats have almost three times as many rods as we do, but 10 percent as many cones.

That makes for killer night vision, but in bright light, those rods become overloaded

and can switch off completely.

That leaves the handful of cones to do the heavy lifting, which makes for pretty paltry

daytime vision.

And those huge eyes?

They're really hard to focus.

To zero in on a nearby object, you need to bend that hard part of your eyeball, called

the lens,

enough to reshape how light enters your eye.

You have muscles in your eyes that can do that quickly when you need to focus on something

close up.

But the massive lenses in cat eyes just aren't as flexible, so they don't bend as well

as yours do.

Ultimately, this all means that cats simply can't focus on anything closer than about

25 cm to them.

So when you hold a treat in front of kitty's face, all they see is a washed-out blur.

Luckily, their sense of smell is twice as sharp as yours.

So if you hold that treat long enough, they're bound to sniff it out eventually.

Trump Voters Realize That Republicans Are OK With Corporations Poisoning Their Kids - Duration: 4:07.

Trump voters all over this country are the ones who have been the most adversely affected

by the policies that have come out of this.

Trump administration, farmers in the United States had been the hardest hit with his trade

wars families in low income areas, low income states.

Red Counties are the ones who were the most adversely affected by the environmental pollution

that he is allowing to increase here in the United States, and that's where we are right

now, and unlike a lot of the farmers who have been impacted, the people who have been impacted

by these corporate toxins are actually starting to turn on Donald Trump and the Republican

party specifically according to a new report in salon voters in Indiana's Johnson county

now for years in Johnson County, there has been this toxic plume of tri chloro ethylene

TCE.

This has existed long before Trump came into office, but it's highly toxic.

It comes from decreases degreasers and stain removers and builds up a overtime in the environment.

Obama, to his credit, came out and said, we're going to try to curtail the use of TCE in

cleaners and de greasers and anywhere else it's used.

We're going to look into it more.

We're going to study it.

We're going to find out exactly how and why it's killing people.

Well, in Johnson county where this toxic TCE plume actually exists, majority of people

that voted for Donald Trump, and now according to this salon report, they're furious with

him.

Why?

Because their kids are developing cancers and not just cancers as the voters say, cancers

they've never even heard of.

We're talking about glioblastomas.

A ewing sarcoma, which is a rare bone cancer, uh, acute lymphocytic leukemia.

These are children about 20 of them so far just in the last couple years who have developed

these rare and often incurable cancers as a result of their exposure to TCE.

Now again, Trump didn't put the TCE there, the TCE wasn't put there during the Trump

administration.

Let's get that out of the way.

But the Trump administration did come out and roll back those TCE rules that the Obama

administration had put in place.

They're rolling back rules on all sorts of other toxic chemicals, so these parents in

Johnson County and in other places across this country who are having to watch their

children's slowly die from these corporate poisons.

They understand that we need regulations and they're sick and tired of being duped to vote

for Republican politicians who roll back.

These regulations tell corporations to bring on the toxic waste because none of them get

affected by it.

You don't see corporate ceos going and developing glioblastoma bone cancers or acute lymphocytic

leukemia because they were exposed to their own chemicals.

You see it in their workers.

You see it in the children who play in this crap because they didn't know corporations

dumped it there.

You don't see it happening to politicians.

You see it happening to the public and these Trump voters are waking up and they are pissed

off and they have every right to be pissed off as does anyone in this country who doesn't

want to see their children or their parents, their brothers, sisters, friends themselves

develop cancers that they can't even pronounce because we thought it would be a good idea

to let corporations dump their toxic waste in our backyards.

Alchemical Hydra Master Guide - Duration: 8:27.

The Alchemical Hydra is a slayer boss which requires 95 slayer to be assigned as a task.

You need to be on a slayer task to be able to kill it and the only slayer master which

can give it as a assignment at the moment is Konar.

The most efficient way to kill the boss is to use ranged.

The best weapon is the twisted bow.

If you don't have a twisted bow, blowpipe or the dragon hunter crossbow are both viable,

but I would generally recommand the blowpipe over the crossbow.

For the rest of the gear, you should use an imbued slayer helmet and your best offensive

ranged gear.

You will need boots of stone at this boss.

However if you have completed the elite kourend diary, the boots are no longer needed.

For the inventory, you want a teleport to get out after the trip is done, an antidote++

or sanfew serium in case you get poisoned, and the rest of the inventory can be filled

with range potions, prayer restoring potions and food.

If you haven't killed the boss before, I'd recommend taking a ratio of 1:2:6 for range

pots, super restores and saradomin brews.

But once you get more experienced you shouldn't need much food at all.

Experienced players may also want to bring high alchemy runes to be able to stay longer

at the boss, and Rada's blessing 4 can be used to teleport to the entrance of the dungeon

for people who have completed the elite kourend diary.

Bandos godsword can also be considered for special attacks instead of blowpipe as it

speeds up the kill slightly, but most people will probably prefer the blowpipe special

attack instead.

The boss is located in Mount Kaluum on the northwest part of Zeah, in the dungeon near

the slayer master which assigns the task.

Quickest way there is to teleport with Rada's blessing 4, or with the fairy ring code CIR

if you don't have the blessing.

Once inside the dungeon, the boss is located to the northeast.

There are a few mechanics you need to know about to kill this boss.

During the majority of the fight, the hydra will switch between ranged and magic for every

3 attacks of respective style.

So after 3 ranged attacks you want to pray mage, and after 3 mage attacks you want to

pray ranged.

Both attacks look rather similar, but you can notice the difference if you pay attention

to the projectile or the sound.

The prayer blocks all the damage, so you will know if you are doing it right.

The boss has 4 different phases.

At the start of the fight the boss will take 75% reduced damage, but once lured to the

red vent that damage reduction will go away until the next phase.

You will notice a message in your chatbox saying that the hydras defence has been neutralised.

While it is green it can spit out poison pools which you can simly dodge.

At 75% hitpoints, it will turn blue and has to be lured on top of the green vent.

While it is blue it can spawn 4 blue lightnings.

To minimize the damage from them, simply stand in the northwest corner of the room so you

only get hit by 1 of them.

At 50% hitpoints it turns into red and has to be lured on top of the blue vent.

While it is red it can spawn a line of fire which will rapidly follow you.

The fire can be dodged by constantly moving.

Finally at 25% hitpoints it will turn black, but does not have to be lured to a vent this

time.

While it is black, it will switch attack style after 1 attack instead of 3, so you'll have

to constantly change your prayers.

It can also spit out poison again like in the first phase.

During this phase it has a max hit of 52, so make sure your hitpoints isn't too low.

And that is all you need to know to be able to get your first kill.

If you die at the boss, your items can be reclaimed outside the boss room for a fee

of 100k.

You will need to bring a new pair of boots of stone to be able to reclaim your items,

so don't forget those.

Now for the tips and tricks!

At the start of every subsequent kill, you want to stand in the southeast corner so the

hydra instantly walks on top of the vent when it spawns.

Alternatively you also can run out of the instance to respawn the boss quicker, but

this will despawn any items in the room as it is an instance.

This is only worthwhile if you are quick and have empty inventory spaces for drops though.

The first attack of the kill it uses is random, but its mage attack has a higher hit chance

than the ranged attack so start by praying mage.

You can predict when the hydra will use its special attacks.

The rotation is 3 regular attacks, followed by a special attack, followed by 9 regular

attacks, and then it repeats with the special attack again.

Each new phase restarts the rotation.

If you lure the boss to the wrong vent, or simply lure it to the next vent too quickly

before the hydra changes colour, it will gain offensive power.

However its defensive powers seems to be unaffected, so it can be a good idea to lure it onto the

next vent too quickly to speed up the kill if you plan on praying perfectly against its

attacks anyway.

Each time it gets hit by the beam with the wrong colour, it gets a 6.25% higher max hit,

but this is capped at 50%.

It's also worth noting that the double-attack it uses on the green and blue phases only

have half the max hit compared to the single attack it uses on the blue, red and black

phases.

During the black phase it will always gain the 50% power, and luring it on top of the

vents seems to not change anything.

The best way to dodge the poison pools during the green phase seems to be to stand northeast

of the boss, and run towards the next vent right as the hydra starts spitting them out.

Alternatively if you don't have the best setup and don't start the blue phase too quickly,

you can also run through the hydra which is another good way to easily dodge the poison.

The best way to dodge the blue lightnings on the blue phase seems to be to first lure

the hydra on top of the blue vent early.

Then stand in the northwest corner, in the exact same spot as in the video.

When the lightning gets close, go 1 step southeast and then instantly 1 step north to make the

lightning stuck under you.

This does not despawn the lightning however, so if you move away, the lightning will start

chasing you again.

This technique requires tick perfect timing, but you don't take much damage if you fail.

When the red phase starts, the lightning under you will disappear and you no longer have

to worry about it.

At the start of red phase, it is smart to go to the southwest corner so the hydra moves

next to the wall.

This means it will have to spend a couple extra seconds getting to the middle when it

starts doing the flame attack.

You can attack while being chased by the flame attack, and doing so with a twisted bow isn't

too hard.

It can also be done with a blowpipe by simply moving 1 tile between every attack.

If done correctly you should take no damage from the fire.

The first attack on the last phase can be predicted and is always the opposite of the

last attack on the red phase.

So if the last attack was a mage attack, the first attack will be ranged and vice versa.

And to finish off, just like any other boss, the twisted bow will hit it a game tick earlier

if you stand within 2 tiles of the boss when it dies.

And that is everything you need to know to become an expert Alchemical Hydra slayer!

With the best setup you can expect to get about 25 kills per hour.

That means 33k slayer, 132k ranged and 44k hitpoints xp per hour.

If you don't have a twisted bow and dragon arrows, and instead use blowpipe with adamant

darts, you can expect about 2 kills less per hour.

With a big thanks to the clan Oblivion and some of my friends, we've compiled a drop

log of over 10000 Alchemical Hydra kills already!

This allows us to estimate drop rates and calculate how much you can expect to profit

from the boss.

Supplies used per hour with twisted bow and dragon arrows seems to be about 400-500k.

With the Hydra claw valued at 80m, Brimstone ring valued at 11.4m and Hydra leather valued

at 16m, you can expect each kill to be worth 243k gp on average.

You will most likely not bank the bones however, so you are probably more likely to loot 236k

gp per kill.

At 25 kills per hour, that is almost 6m gp loot per hour, which would be about 5.5m gp

profit per hour.

Keep in mind that at the time of making this video, the content is still new, and prices

of new items are likely to fluctuate a lot.

But even without the unique items, you can still expect to profit over 2m gp per hour

from the regular loot.

Anyway that is everything, I hope you found my guide useful.

Good luck and happy hydra hunting!

[Rion's Sanpo 2] Osaka, Midosuji walking with local guide!! #095 - Duration: 9:43.

That was used to be the bouldering space

Osaka's local baseball team win you know, they have a parade right here

somehow, you know, it is really popular for the foreigners

Hey guys, welcome to Rion's TV I'm Rion

So today I am at the Namba station if you see my several videos its familiar, right?

today what I'm gonna do is Rion's sanpo part 2

Rion's sanpo is pretty much take a walk around here and speaking of something I found

it's gonna be interesting and you can know about Osaka more. Okay, so

Let's take a walk

Well so I'm front of the Namba station and the front of the Namba station as you see there is a tall building right here

That one is a department store called Marui

well if you check my how to find a restroom in Japan easier then you can see the building inside how it looks like

Well, that's a tall building. There are so many stores right there

Also, you can find a restroom easier. However, you know, you have to go up to the second stairs

It's kind of bother huh? Yeah, that's pretty much what I explained.

Okay, so let's keep going to walk

Well, so I am at the Midosuji right not you see the street right there right that one is called Midosuji

as you see that's a one-way street and this Midosuji is the biggest one-way street in Osaka

Well, usually Japanese roads are pretty small, but this Midosuji

It's even the one-way street. However, there are five to six lanes

Yes, that's a huge street

If you come to Osaka, you may realize that you see the subway names Midosuji line

That's we call it. You know the Osaka's blood line

Because that's the main subway line. This is the as I told you that the biggest Street Midosuji right?

You know like pretty much any kind of celebration They make a parade right here

Osaka's local baseball wins, you know, they have a parade right here and

Sometimes the Olympic players win from Osaka, then. Yes, they make a parade here as well

So that's the Midosuji and then if you cross street in that way then you can find Tanimachi suji

Which is opposite one way, somehow that's really popular street as well.

However Midosuji is popular compared to the Tanimachi suji

Also speaking about the osaka osaka mainly divided by two parts one is Kita, other one is Minami

So which means it's in the north part, and the south part

Osaka station and Umeda station Those are the Kita part and also we call it Minami

Minami means south part which is this Namba area and

The one I show you in the video about the Tsutenkakul, you know Tennoji. That's the Minami area

And then, you know pretty much in Osaka people divided by that two parts, so

People from the north part they usually go to the Osaka station, Umeda staion

But People from the south part of Osaka, people usually come to this Namba station

yes, so That's how it works

Look at that Well, you know what it is

Yes, that's a pachinko store as I told you in the Pachinko is a serious program in Japan's video

There are so many pachinko stores around Namba station.

So, you know, you are gonna surprised how many Pachinko Stores we have at the Namba station

if you're interested in please check my video

Well, so this is the Midosuji. Well, so actually this street is next to the Dotonbori

so if you see this video and then also my Dotonbori video, then

Pretty much, you know about osaka, but then it's only Minami though

well so you see that building right there that one called the Namba hip

So that's pretty much the building for entertainment as you see there are many floors right?

even though that's a tall building They just have a only entertainment stores, such as KaraOke, Pachinko stores

And then Internet caffe or something like that

Well, you see that one right? There is something over there, right?

Actually that was used to be the bouldering space as you see that's a huge street

Anyone can look at that Boulder space

So that would be the super good attraction

However, you know, they get several accident, unfortunately, so they close it

I've never seen someone doing a bouldering right here. Well, I don't like the high place

So I really don't want to try it, but then that would be so good

But then, of course, you know

If someone get the accident right there and someone dead they have to close the department stores as well

Well, since they spend so much money for building that building

So, of course, they don't want to close it down for only that attraction, you know

so that's a pretty much reason why they closed the attraction by there

Yeah, it was like a 10 years ago or even 15 years ago, I think

Well, you see that the store with dragon that's Kinryu one of the most popular store is Robin Ford

Well, as I told you even this is not the main street compared to the total body

But still there are so many people walking around here, right?

Well, so you see the store right there as you see there are so many people waiting front of the restaurant

well, so I think that's the store sells the beef bowl I think?

Its like Yoshinoya, but then some hou recently so popular for the foreigner Well, I don't see much

Japanese people waiting for in the line, but somehow, you know, somehow it is really popular for the foreigners

Yeah, so this is the store

do you see that? even though there's a Yoshinoya which is my favorite restaurant

they prefer that beefbowl

I'm pretty sure that Yoshinoya is a cheaper than that and

Yeah, I guess pretty much it's gonna be like half price

Still people want to have that beef bowl compared to Yoshinoya

Recently, you know you can eat the Yoshinoya pretty much in any country so

So I'm at the bridge right now

This bridge called "Hikkake Bashi" Well if you come to Osaka, maybe you've seen

This guy right here

Yes, that's a popular one, right?

Well as I could you that Midosuji is next to Dotonbori

Maybe you can't see that much but then that's the place where you can find the popular guy

There are so many people right well today is Saturday so a lot of the travelers from foreign country and the from Japan as well

Well, so this is the Donquijote I think there are three Donquijotes around Namba station

It's so popular for the young generation

Well, I love that store as well

Well, so if you keep walking straight towards that way you can find Shinsaibashi

if you keep walking straight, maybe like 30 minutes more then you can get to the Umeda station, which is Kita area, means north part

Well, so I think today it's pretty much that's it
