- You’re a bank robber trying to escape from jail. Can you solve the riddle to get past the fence to freedom?
--
Your timing made you and your partner infamous bank robbers. Now, you need to use that timing to break out of jail. Your partner is about to flash you a signal, and exactly 45 seconds later the electric fence circuit will short out. Then you notice that your watch is broken, and all you have are two 1-minute fuses in your pocket. Can you time your escape and get free? Dan Finkel shows how.

Good for a rough estimate, but you need something that misses by less than a second or two--something reliable.
You know that the jail is housing weirdos when the prisoner can
A) move Super fast
B)unable to count to 45 seconds and
C)knows that the fuse burns for exactly 60 seconds even when his watch is broken
ikr! Who can get outside of that fence in one second!?
can you count exactly 45 seconds
@@estherqin3080 the question is who can't?
@@brunobottoni9661 You can count, but you have no guarantee that your counting is an infinity precise measurement of time. For example, I tend to count seconds more quickly between 1-10 because the English words are shorter, and the counting slows down as I move to numbers bigger than 20.
If you doubt it, try asking other people to count off a minute by the second and compare it to your watch. They're going to be pretty close, but I wouldn't be surprised if they ended the minute off by a second or more.

I really appreciate that Ted Ed has riddles for different levels and skill sets. I have a traumatic brain injury, so I like to watch their riddles from time to time; it helps to keep my brain stimulated. Some days I have worse symptoms than others and I can hardly even speak. Other days, I almost feel like my old self again. Thank you for this. :)

That’s great ^_^ I’m so glad to hear that.
Step 1: check if the fuses have green eyes.

FBI open up
Plot Twist: The jail knows that some prisoners will try to escape using the method and makes each fuse burn out in 59 seconds. This means that the prisoners will go through the fence three-quarters of a second earlier and get electrified.
Second Plot Twist: It takes a bit longer than the prisoner in question expected for him to light the fuses and he ends up timing it perfectly.
Just a quarter of a second earlier actually I know I'm nitpicking
_ok_
__look_
Plot twist the outside of the prison is the real prison
hey everyone! ted ed is teaching us how to break out of jail! lets take notes!
Good idea😂
Step 1: have an accomplice who wasn't arrested and is somehow able to disable the only security measure.
didn't try to solve the riddle because i can't help a criminal escape jail
YOU are the criminal.
Well you failed anyways lmao
The current 2 replies get a woooosh from me.
@@dominickeijzer5844 lol no, i meant he got out anyways so he failed from keeping him in jail
Poor excuse.
Push the guard into the electrified fence. When it shorts out ,simply climb over it to your awaiting getaway ride.
Thats thinking outside the box
Sounds good. But in an ideal world, that'll draw attention.
@@sei-zero I mean, so would a prisoner running outside the fence.
Or you could just count
Improvise, adapt, overcome.
Prisoner: Doesn’t know how to freaking count 45 seconds
Also prisoner: Knows that fuses he had can burn in exactly 1 minute and counts exactly the time where the flame should meet a certain destination
Maybe because he tested one BEFORE he knew about the escape plan? When his wristwatch was still working?
But isnt a jailor the person who runs the jail?

hardly anybody can count exactly 45 seconds you always get to the end too soon or too late for it to be exact

Ted-Ed: “looking for a harder puzzle?”
Everyone: “how many times we gotta teach you this lesson, old man?!”
Millions times
Narrator: But his watch is broken.. how can he tell time with fuses and ligh-
Me: 1) who gives their prisoners freaking watches and 2) Just count physically!
Also, he could probably use the watch to short out the fence himself (sticks to bring the wires close enough, then a tap with the metal)
And also, who gives prisoners lighters and lets them make fuses????
3) Why is there even a watch repairing station
Have you ever tried to count any amount of time longer than 10 seconds and then checked your watch afterwards? You might get close, but it's very rare and very difficult to get it exactly.
Starting fires in front of prison guard right before your escape. Hmmm... My gut tells me this is a bad plan.

I really like how they convert a small looking boring puzzle into an awesome puzzle by indulging it into some random story.

This is easily one of the best puzzles I've seen here. I took forever trying to solve this before finally giving in and unpause to see the answer I never thought of and then TED-Ed goes to say "Looking for something a little trickier?" :/

I have a habit of counting down the time in my head along with a timer without looking at the timer of course. I usually ask myself "Will I ever need to be able to count down as accurately as possible?". Now ted ed has given me the answer.

@@justjess-zl3pm No. Absolutely not
Damit u could count
Here are 2 quick riddles for u.
1. The two doors
You are in a room with two doors - a red one and a blue one. One door leads to freedom, the other one leads to a ton of worms that you have to eat if you open that door. There are two guards in the room - one always tells the truth, the other always lies. The guard that tells the truth knows that the other one always lies, and vice versa for the other. Both guards know which door is to freedom. You don't know which guard is which. You may ask one guard one question. What question can you ask either guard to guarantee that you go through the right door? The answer is below.
Pretend the red door is to freedom. The question to ask is, "What door would the other guard say is to freedom?" This works because if you ask the guard that tells the truth, he knows the other one always lies and would say the blue door, so he truthfully replies, "The blue door." If you ask the guard that always lies, he knows the other one always tells the truth and would say the red door, so he lies and says, "The blue door." So, they both said the blue door... so go in the other one!
2. The three light switches. In the attic of an old house, there are three light switches. They control three lightbulbs in the basement of the house. How can you figure out which light switch goes to which lightbulb while only going in the basement once? The answer is below.
Turn the first two switches on and wait ten minutes. Turn off the second one and go in the basement. The lightbulb that is on is connected to the first switch. Then, feel the temperature of the other two bulbs. If it's hot, that bulb is connected to the switch you turned on, then turned off. If it's cold, that bulb is connected to the switch you never touched.
This took half an hour to type, (on mobile) so please like for my effort! Hope you enjoy your new found knowledge!
First riddle not only very popular and well known, but I believe they already covered it. The second one is pretty cool, though.
Dangg.. I saw first riddle long ago, but couldn't find or think of the answer. Thanks for that!
I could get the first one. But I solved the second one. thanks for this mate!
@unknown ent1ty yeah, but then you wasted your one question and you have a 50/50 chance of success
The first one I know and solved a long time ago, but the second one is new to me.
My brain thinking: JUST BURN THE FENCE
me: but that is going to take ages
My brain : ... do you have a better idea
me: in 3 seconds yes
I’ve watched Ted’s puzzle for the first time.
This is a very interesting video!
I wanted to know the puzzles’ existence earlier
Very good ! Not just the idea and the script but also the production. Congrats🤞
I tie the lighter to the end of the fuse, and use my knowledge that a standard Bic lighter is 8cm long to measure out a 25cm pendulum.
45 swings and I go through the fence.
truthsmiles can you even get 45 swings out of a fuse and lighter pendulum
That only works without air resistance
How does it work tho? 1 swing from a 25cm pendulum made by an 8cm lighrt is perfectly 1 second?
Jam Ham Time it’s funny. Calculating the period of a pendulum is surprising complicated.
I don’t know what you know, it was a bit complicated for me, as I’m not very fluent in introductory level physics, but if I remember:
You can think about gravity being the only non perpendicular force to the pendulum (if we ignore air resistance) and that will lead you to some sort of:
angle’’ = a* sin (angle)
Where angle’’ is the second derivative and a is a constant.
This equation is one that I’m not sure there has been a solution to.
So you probably won’t really find the exact algebraic solution to the problem. What you can do is approximate sin function around the angle 0 as a polynomial and try to use a pendulum that uses small angles as to keep the approximation the most accurate. With the approximation the differential equation can be solvable.
The way others go is through conservation of energy, potential and kinetic energy considerations you can easily get an expression for the pendulums velocity at any angle.
Great, so we can just integrate that expression to find the angle over time right?
Well yeah but again I think it’s an unsolved if not impossible analytical problem, it ends up being an expression we don’t know a primitive for, and a such can’t integrate.
The final answer is yeah we can use some sort of approximations in various ways and easily get good approximations, especially with the use of computers.
But it’s annoying for me at least, there doesn’t seem to be an exact analytical solution.
Which is what this problem was kind of asking for.
For a real life robber, one might know an approximated formula for a pendulums period that is has an error much smaller than the 1 second or so the robber has to pass the grid though.
@@aienbalosaienbalos4186 That guy...is a robber.
@@aienbalosaienbalos4186 i think it's the conservation of energy that should help, which gives us that the potential at the top must be equal to the kinetic at the middle. Height reached = L * (1 - sin alpha), but then i've forgotten what the trick was for finding out the speed through the mean position. :">
Apparently, the formula we should get is T (in seconds) = 2 pi SQRT( L (in meters) / g )... so we get a length of g/(4 pi²) ≅ 248.237 mm. So now, @Ipek... what happens if the fuses are slow-burning, thus with a length smaller than what is needed for this? 😈

*_in the end the jailor dies a sad death, due to do fact that he was busy freaking burning fuses, instead of simply counting it by himself..._*

You mean prisoner. Jailor is in this case the one dozing while leaning on an electric fence and somehow not getting electrocuted.
Actually due to sleeping next to the fence.

I love ted ed riddles
I swear, I’ve been binge watching Ted Ex video riddles. I still have a lot of workschool to do.
everyone be gangsta until guard takes away his lighter and fuse
More than the riddle itself.. I congratulate you for the art and work you always deliver!!!
Domo!!
I absolutely enjoy these fun little riddles!
Thanks TED-Ed! This helped me a lot in prison!
Could you really depend on a fuse being that accurate, down to the very second?
And then you notice,
TOYOUR HORROR!
that ur watch is broken XD
This one's a classic in my family! So proud to be able to solve it! 😊
This is brilliant!!!
Excellent! Keep it up.
This dude has the best voice
Who?? The robber
Here is another solution: Although the fuse burns irregularly the amount of gas used by lighter should be constant. You light one fuse and keep the lighter on constantly until the fuse burns out. You note starting level of gas and finished level of gas and that distance is your one minute. You divide it into 4 and 3/4 of that will be your 45 seconds. You then turn on the lighter when you see the signal and once the level drops by 3/4 of a minute’s distance, you got your 45sec. Though I realise there is a flaw in this logic that the amount of gas used up in 1 min will be small and hence impossible to measure 3/4 of that amount accurately, but that would be another way to solve it if time to be measured is longer and the lighter is transparent:)
I think the idea is that you only realize you lost your watch right before the signal
If cut a fuse wire into half i ll get 30 sec fuse .and cutting the 30 sec fuse i ll get 15 sec fuse.now i have 30+15 sec fuse ,after the 30 sec fuse burnt out lit the 15 sec fuse .This is my idea tell me if iam wrong
ppl in these riddle videos: criminals, hostages, giants, dwarves
ted ed: and they were all raised perfect logicians
I have been binge watching these videos.
The aesthetics are amazing in this!
What will I do if the lighter doesn't work with me from the first press!
That’s when you start counting
you can also double the second fuse twice making it burn in 15 seconds
FINALLY! One that I know how to solve prior to the solution :D
I'm trying not to be too proud of myself for getting this one.
2:48 He was holding the wire for three seconds
Me, an intellectual : Throws the fuse and lighter away, starts counting 45 seconds in my mind.
But those 45 "seconds" could be 44 seconds or 46 seconds.
Pretty cool. More please. 😀
I think this is the first riddle I’ve been able to solve!
Does the answer write anywhere? Or can you write it? :) I can’t seem to find it in the comments
This is the first ted puzzle I have solved without pausing (note : I have never solved one earlier)
If you make even a small mistake in counting off 45 seconds, you’ll die. But luckily the amount of time it takes for you to light the fuses doesn’t count, so you can still be way off exactly 45 seconds. And you don’t have to worry about the wind blowing out the lit fuse or watching your back for cops and prisoners so you can stare at fuses for 45 seconds.
Finally solve this riddle!
Ted ed is my favorite CZcams channel and the video's is also very interesting
Wait...
WHY AM I IN JAIL HUH?
counting to 45 seconds:
ted ed: lets pretend that never existed
But if the timing has to be that precise (within a 1-2 second margin) you might as well just count to 45, since timing the fuses would be just as hard as counting to 45 give or take 2 seconds. The precision of lighting the fuses the INSTANT it dies will be just as precise as counting to 45.
I SOLVED IT WTH THIS NEVER HAPPENED TO ME
Carl aM agic omg cool
Congrats!!! 😆😆😆😆
We’re all proud of you
I should hope that you've never escaped from prison....
SAME!
Hmm. I tied the lighter to one end of fuse A which I tied to something else (perhaps my finger). I lit fuse B, while dropping fuse A and counted the pendulum swings for the 1 minute duration of fuse B. So, 3/4 of that number of swings is 45 seconds... which I can perform any number of times because I never actually burn fuse A.
OrbitalBliss Genius! This is far more easy.
They said “precise”, not to mention the fuses aren’t threads, and that the oscillations will die out very soon.
So underrated comment
Thats more of a vacuum situation since there would be other factors into play like wind, viscosity, gravity and stuff. So might not be exact. But that's really creative.
@@Monkeynertia Also the fuel in the lighter would keep opposing the motion of the pendulum here so, will literally kill the oscillations too soon!
Man i miss riddles like these that could be solved with intuition, the new ones are all just massive maths problems
