I sawed this boat in half

yeah you are absolutely right my guy, thanks for pointing that out. thanks for dooming the entire world scientist

You mastermind!

there's a reason why he put on a suit, just through it into the last room when you leave or something

@@victortang5076 he still cant get out witouth letting the rona out

Add in the fact that its airborn, and it becomes twice as bad. You dont even have to talk to someone to spread it, you can walk near them and the have a chance of getting it.

exactly my same scenario, except it's only 2:40 currently

I had to get a pencil and paper to solve it but yeah they’re hard

Its 4:01 but i knew it was immosible i finnaly solved it but my brain is dead rn ama go sleep

21:52 this is pretty much the only one of these riddles I've ever solved.

LOL

Ya

Lol

Accurate

LOLLLLLLLLL

Lol why did i laughed so hard reading this

Lmao...me too

I just gave up and made him clear all rooms and kill himself in the middle.

LMFAO WHY DID I LAUGHED SO HARD LOL

Lmaoooo

Yeah that's true, nice job!

EXACTLY! That was my solution, in fact!

@Snowmon89 I'm sorry to tell you that your idea fails twice ! -Firstly, you don't have time to come back to the first room every time ! 1:14 1:22 you can see how the instant concrete takes just a few seconds to completely fill the room! - Secondly, let's say you are starting in room a5 (1st column, 5th row from the bottom) After you pull the lever in room b5, you can safely return in room a5, but after you pull the lever in room a4 , you CANNOT come back to the starting room. If you did that, you would be STUCK ! 😂 (And also, you would break the rule "Once you enter a contaminated room, you must pull the switch" ! The first room is not immune to the virus, so it would become contaminated as soon as you move from room b5 to a5) =)

​@@francescof3267 Well, no. You are in fact wrong. If you go from A1, all the way down to A4, flicking the leavers in 2 and 3, you can still path back up to the starting room with only overlapping the starting room. So their statement is true that the only thing preventing it is the end room requirements. You seem to be stuck that you have to loop back to the starting room every flip, instead of leaving the double-back till the end.

I believe he was saying that the first room sealed behind you so you could not escape or something like that.

More like fine milk lmao

@@RafaelMunizYT I wasn't quoting a subreddit

@@eggyrepublic fair, it's just because most of the times I see people mentioning it they're talking about the subs

you mean milk

Indeed, the way I see it, when people use the expression “aged like milk”, it’s the exact opposite of saying “aged like fine wine”, because unlike wine, milk is something that always ages poorly.

Legit most underrated observation ever

Greetings fellow CS gang

Oh that cracked me up too 😂

I don't get it

@@adumba3709 This puzzle is similar to the infamous travelling salesman problem. "Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city exactly once and returns to the origin city?" Right now, there is no generalized solution to this problem and must be brute forced to solve with the given parameters.

I can’t even solve one

Oh oh 4:05

Agreed 🎉

@@tax-evasion-official *Sanctuary Guardian plays*

No no, you have to ask the virus, "If I asked to leave, would you say Ozo?"

Hmm green eyes just like that prison island riddle

Continuation: The virus lets you go and then escapes the lab, which was located in Wuhan.

@@coppertones7093 oh ok lol

The alarms go off here, because the power is still out.

Probably on purpose, as it was in the permafrost

Phosnerd reasonable

Definitely

Maybe it was an illegal lab 🤔

that's a good point OwO

Damn budget cuts

thank you jeff kaplan. But have you forgotten? Who will make the amazing overwatch updates now? This is worse than a zombie apocalypse!

Yeah, exiting the exit room would kinda destroy the world... so don't exit the exit room.

so that's why you haven't made developer updates or posted on any forums recently

I went around and destroyed every room, including the exit room, before reaching the entrance room again and exiting through the entrance.

I guessed that answer

The first question I had is why that alarm didn't immediately close all of the vents?

'sorry bout' dat'

Neither did you make it

"It was made in a chinese lab and isn't real"

@@surelock3221 No

@@The_Imperatrix yes

@@surelock3221 even if that was confirmed to be true, it wouldn't solve anything.

@@trickytreyperfected1482 you missed the point. It can't be true. The first part of the statement states that the virus was made in a chinese lab. The second part says that the virus isn't real. If the second part is true, then the first is false, because it assumes the virus isn't real and thus, it wasn't made in the first place. The statement requires both parts to be true at the same time which is impossible, so, the statement is false.

Looooooooooooooooooo

Lllloooooooollllllll

dont feel so bad about yourself, all the comments may have been done after the video and they could be liars

ikr. It was the first riddle I've actually solved ;_;'

Suhas Gondi I did this riddle once and Succeeded but now I forgot how I did it so now I came back after a long time and I tried once again but I failed lmao

Suhas Gondi i actually got the fact that you could go back but i didn't find a way to like the route so i still failed

Suhas Gondi Or just lied about it

KM true

Screw that, I finally solved one

KM i think the easiest one is is the pyramid riddle

Alvaro Cerda, exactly my reaction after solving it for the first try.

KM nice man... now i dont feel as smart as i did :(

Hahaahahahha

But then there would be no fun🙁

Then the toxic chemicals will travel in the blast if you're talking about explosives, however, if it is the solidish liquid that they showed in the video, it'll work great if it's near the exit.

Rossie Ivanova whats so fun about a virus lol

Bluє Príncєѕѕ •. It's not the virus, it's the riddle. If there was an easy way, there would be no riddle => there would be no fun. So, that button is out of my picture😊

You commented the exact same thing on another riddle video lol.

1:42 you missed rule 3: you must pull the switch before you can leave a contaminated room

Same

I just like the scenarios

I solved it. Almost immediately.

Me every time (except for that one time where I actually managed to solve the ted ed riddle that was apparently written by einstein)

@@marteater19zz SO ITS YOUR FAULT THE VIRUS ESCAPED!

pandemic* epidemics are within a small area, a pandemic isnt lol

@@fenderfrontman epidemics are viruses that cannot be stopped and are mostly dangerous, like the flu.

But you destroyed the entrance.

@@Modelta I think that's called an endemic

@@justaguywhocomments4795 maybe, i dont know

Actually yeah they could install an ultimate destruction switch on the outside requiring fingerprint retina and password identification to access

Guys it’s a riddle.....it’s not a real story........but just a riddle to check how smart u are or to learn something

Also Its kindla iditotic to not lock those vents

They got Riddle makers to design the building instead of architects with experiance in biological containment construction. Probably why the virus got out

Right? Kind of comes off as an intentional design flaw

made me paranoid because I thought I was doing it wrong

The only riddle I've solved here is the Einstein riddle. Don't ask me how long it took.

Nathanael Perez How long did it take?

the only one I solved was the green eyed one. the rest are basically a foreign language to me, but I still love them

😑😶😐

The virus must be pretty fast since it took me 3 minutes to solve.

Liam Rochon I solved it instantly...

And thus the story of *Plague Inc.* begins.

the first room doesnt get contaminated by opening the second room.

@@weisstcg at 4:23 it states that the first room "may" be contaminated from opening up the second room (twice I may add!) and while that doesn't matter since the first room will be destroyed, you can't deny that same chance applies to opening up the last room to the world

@@redfluxbluedawn414 you're right, faulty story. it seemed like they were adding some kind of context so that you have to blow up the first room but they didnt think about the overall story lol

But the LORD said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for the LORD seeth not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart. 1 Samuel 16:7, now how do we distinguish these people?

I think you are right!!

airlocks. They are wonderous

The airlock won't help if the air gets contaminated when the lock is open.

The reason why the entrance room got contaminated is because the air lock was opened for too long but from the exit it is opened once so there is no contaminating the environment

If the exit room has a negative pressure (like modern operating rooms), then when you open the door for a short period of time, air is sucked into the room and the virus does not really get out. Minus the ones on your clothes of course.

Congratulation!

You’ve prevented an epidemic of apocalyptic proportions!

Third time for me, it’s always so hard

Me too!!!

This was the first time my dad could do it... because this was the only one my dad watched LOL

Me who watched every last one of those Ted-Ed riddles and knows all the answers to the riddles: *I'm 4 parallel universes ahead of you*

lol so true i solved like one but it was a bonus riddel

yooo bro sameeeeeee

Osama Jweihan - Computer scientist here. In fact, if you proved that the Hamiltonian path problem could be solved in polynomial time (i.e. faster than trying every possible combination), you would simultaneously prove that EVERY problem categorized as NP-complete can also be solved in polynomial time. Similarly, proving that it cannot be solved in polynomial time simultaneously proves that all other NP-complete problems cannot be solved in polynomial time. Solving this problem pretty much translates to instant fame btw, as it has eluded computer scientists for quite a while now. The current concensus is that all NP problems cannot be solved in polynomial time since otherwise we would have found an efficient algorithm for at least one of these problems, but such an argument is not a very rigorious proof, and it's still technically possible that humans have just been too dumb to find an efficient algorithm yet.

I agree, this is too easy 4 me.

ravi soni yes it's the first one I have ever figured out on my own

ravi soni agreed

ShadowPlays 2 cute profile picture lol

But if you open the door to the contaminated room, the previous room may get contaminated

Same idea

@@CaptFrost-ed8ij ohhh, i think he thought of a new puzzle! How would you make it so you destroy the contamination, while also leaving the building, and having destroyed all of the contamination without it being spread to your previous rooms with you and to avoid it from leaving the building as well

Scientists

The real question is why the vents open when the virus is leaked.

@@internetperson9813 I agree, that is a horrible design!

@internet person then remember all the room except the 1 room is contaminated if you leave the exit it will spread The virus anyway without decontamination room. you remember if you back track back to the first clean room After pulling the lever. it still contaminated the room on the right and have to pull the lever the first room to move down a room.

Or not build a lab with a virus we are vulnerable to in a place with earthquakes.

thats how coronavirus got out

It has an airlock
