Difficulty:** (1.4)
Submitted By:pennyisgifted*




A man is trapped in a room. The room has only two possible exits: two doors. Through the first door there is a room constructed from magnifying glass. The blazing hot sun instantly fries anything or anyone that enters. Through the second door there is a fire-breathing dragon. How does the man escape?


He waits until night time and then goes through the first door.

Okay, I see that, but, with only two iccky doors, how did he get in there in the first place?
Aug 18, 2003

haha good one!
Aug 23, 2003

I thought that was funny
Aug 24, 2003

That was good! Funny how it's not the first thing to come to mind!
Aug 26, 2003

Wouldn't this be better in the Situation section? Good one though.

Aug 06, 2004

At first it was serious but the answer is hilarious.
Jan 06, 2005

It could be either since fire breathing dragons dont exist.
Jan 06, 2005

its nice and very funny keepup the good work!!!
Jan 06, 2005

Jan 06, 2005

Darn, what a simple answer. Not the one I thought of, thanks for the fun.
(user deleted)
Jan 06, 2005

You didn't say how big the doors were so I assumed he opened both, hid behind one and hoped the dragon wandered into the other room.
Jan 06, 2005

A friend of mine listened to the answer and then said, hey - in that case the second can work too.

Wait till the night when the dragon is asleep.....

Jan 06, 2005

i like
Jan 06, 2005

it was really cool, iwas i the craziest answers, the guy would open the door with the magnifying glass first and open the... and that was as far as i got . but the teaser was awesome !
Jan 06, 2005

That's so easy!!!!!!!!! great one!! lol
Jan 06, 2005

Hey, I got one. Sort of. I thought to wait until it was cloudy.
Jan 06, 2005

Yes they do, SLICE O PI.
Jan 06, 2005

Good one!I first thought he'd get the dragon to go through the 2nd door.
Jan 06, 2005

HAh.. Great one! Thats the hardest - find the simplest soluten great fun!
(user deleted)
Jan 06, 2005

1st to jump to mind is laet them fry each other out and you can have a choice of WHICH EVER door you want
Jan 06, 2005

That was a tough one for me. Lately they have all been hard for me, but I enjoy the challenge!
Jan 07, 2005

Nice One!!!!!!!!
Jan 07, 2005

got me
Jan 07, 2005

kk, it was good, but i've read better, naah, it's cool
Jan 07, 2005

kk, it was good, but i've read better, naah, it's cool
Jan 07, 2005

I must be really stupid if I didn't get that
Jan 07, 2005

My first thought was the first door... Because he wasn't entering... He was exiting, right? But the answer was still great. Good job.
Jan 10, 2005

mivich, i thought the same thing, but a little different--open the first door, then go into the room with the fire-breathing dragon (whether or not they exist... ) get him to chase you into the middle room, and hope he goes into the other room and gets fried. then you could easily exit out the now-vacated room! HA! whatever, i thought it might work.
(user deleted)
Jan 24, 2005

It deapends, what speases you are.
Jun 10, 2005

quite good one. got quickly tired of it then clicked 'answer' and just before it appeared i got it!!
May 26, 2006

Oh, that is so funny! You got me. I was thinking along the lines of removing the door to use as shield against dragon fire or sun. A great teaser!

May 26, 2006

A good teaser, with a fine common-sense solution! However, it is presumed that the man had a clock or watch to indicate night time, and also he knew which door led to what effect!
May 26, 2006

You almost got me. Good one.

Let's send Imurray out the dragon door.
May 26, 2006

Fairly obvious. Problem is a very quick piece of logic though says that for the magnifying room to be effective it would have to focus the sunlight, which means that the room would either have to move constantly, or, more likely, if he waits five minutes the sun will have moved enough that the light diffuses and he can walk through even in sunlight.
May 26, 2006

I really liked this one.... Imurray wake up.... dying to hera what you have to say!!!
May 26, 2006

Good teaser. Blagh you said that ...'the magnifying room to be effective it would have to focus the sunlight', Sorry this is would not necessary so. Only a limited focus would bring the temperature into a fatal range regardless of the sun's movement. See the greenhouse effect on Venus.

All of you nay Sayers, these are only games or puzzles, not science lessons, nor some source of deep enlightenment. Have fun with these and don't take yourself so serious, I'm sure no one else does.
May 26, 2006

i thought you said the man is trapped. but he can easily open either door. shouldn't there be some kind of lock or something for the man to be considered trapped?
May 26, 2006

Well, I guessed right! But for real, I think it should be something besides a logic, maybe trick, because when I thought of the answer, I thought it couldn't be that because it wasn't a trick teaser. But, looks like some people still had a hard time with it, and enjoyed it, so that's cool. Although I must say I like the person above who said that 'in that case breathing dragons don't exist'! LOL!

May 26, 2006

Could he have opened both doors, stood aside and let the light from the magnifying room roast the dragon?
May 26, 2006

Heck yeah, had to read that twice and after that I got it 1st try! WHOOP WHOOP! i rock!
May 26, 2006

Great teaser! I used to hear all kinds of room teasers from my dad when I was little, so I'm going to have to share this one with him.

MeSighAh - I truly hope you were kidding, but if not just remember that a woman would have never gotten herself into the situation to begin with. (just kidding!!)
May 26, 2006

Good one and I completely agree with AwwwSweet!!!
May 26, 2006

Verrry true awww sweet! I didn't get it. I thought the answer was hilarious!! It's makes a complicated situation seem ssoo simple when you have the answer, doesn't it?
May 26, 2006

I thought it was a great teaser! Keep up the good work!

.... another thought... why do people get so critical??? This is for fun people (MEN & WOMEN)... lol
May 26, 2006

Awwwwwwwww Sweet, thanks for giving me my first laugh of the day!
And just ask reddragon if Fire-breathing Dragons exist!
It was a fun teaser, but I do believe that it may have fit better into a different category - trick might've given it away, but situation would work.
May 26, 2006

Nice one ha ha ha
May 26, 2006

This was a fun teaser!!! Not only because of the visual I got from thinking about a scenario like that, but also because of all the funny comments!! That's the really fun part whenever I'm reading the answer to the teaser every day... I love seeing all the interesting comments! Although I knew what the answer was gonna be right away (wait until night...) it was still fun! I'll give this one five stars! *****
May 26, 2006

It was OK, but it was a stupid answer.
May 26, 2006

I can't believe I didn't get that! I thought it would take a lot more thinking to come up with an answer so I gave up too quick. Good one!
May 26, 2006

There is another solution.
In old China, Han Fei wrote: "The beast called the dragon can be tamed and trained to the point where you can ride on its back." So if that's true, you should tame it, train it, get on its back and fly away.......
May 26, 2006

or sincedragons don't exist, [unfortunately ^.~] he could go through the second.
(user deleted)
May 26, 2006

i was thinking lead the dragon int the glass room, the dragon dies and you can go through his door
May 26, 2006

good one, but I also came up w/ lead/lure dragon into other room, but I liked the answer provided better
May 26, 2006

haha that was really funny!!!!

good one! going into my favorites!
May 26, 2006

sorry but this sounds like one of the 'cube' movies. If dragons exist, how do I know this planet doesn't have two suns? *snarf*
May 26, 2006

It was easy enough for even me to get.....these are a fun thing to do...enjoy!!!!
May 26, 2006

good 1!

May 26, 2006

I was stumped, I thought about the noght thing for a second unconsciencely but it was fun
May 26, 2006

Wait a second! If the room only has two doors and no windows, how does the man know when the sun has set?
May 26, 2006

I really thought this was good! Some of you read way too much into these things.
May 26, 2006

Aha! Very interesting...and unexpected, might I add...
(user deleted)
May 26, 2006

regarding how the man knows if it's night or not - can't he just open the door and look without going in the room? would it not be bright or dark?
May 26, 2006

I thank you. This was fun and your comments are as well.
I thought if it rained the sun would not be out and you could escape through the glass room.
May 26, 2006

May 26, 2006

Real cute Maybe he could call the FIRE DEPT>HA HA
(user deleted)
May 26, 2006

well, i liked the joke, but how did the fire breathing dragon and the man get in there anyway and wouldn't he have a cell phone so he can punch in 911?
May 26, 2006

I thought it was really hard and I thought for a long time and didn't get, and when I saw the answer, I slammed myself...HARD!
May 26, 2006

Very logical all right. I was going to bread the mirrors in the room. How i don't know . Just wait is best!
May 26, 2006

fishmed the first comment has a very good question How he get trapped in there in the first place. go through the mirror room at night too? Just wondering.
May 26, 2006

So easy, that it was a little boring. Still pretty good.
May 26, 2006

Huh... I thought "The way he came in," because you gotta wonder... Just how did he get in there in the first place?

And shame on you guys who said "let the dragon get fried."
May 26, 2006

LOL That was lame.
Lame that I didn't get it.
May 26, 2006

Why can't people simply admit that they didn't get the right answer, instead of finding every possible thing wrong with every riddle?
Dragons do exist in my mind and in lots of other people's too. If the writer says the sun frys anything entereing the room, then in the universe of this puzzle it does.
Great job and a very good riddle.
May 26, 2006

gosh. that was reeeally weird. i didn't get it...i must be reeally stupid.
May 26, 2006

Oh, no, another groaner. In case you have missed some of my comments, that is a slam at me, not the teaser. I always try to read too much into these and then really feel stupid when the answer was as plain as the nose on my face. Nice job! Makes me realise I need to read between the lines sometimes.
May 27, 2006

haha that was good
that was hard cuz it was so simple
May 27, 2006

My guess was the same as MumboJumbo's. Good work!
Jun 01, 2006

it was ok....... could have been better... add more story before u make that kind of answer... just some constructive critism cuz i laughed and it was real good!!!!!!cccc
Jun 09, 2006

Ha! That one got me. Great one.
Jun 20, 2006

Aug 01, 2006

Great teaser! I thought something like... go out the window, but I like your answer better!
Oct 24, 2006

like this one made me laugh. and say Doh
Oct 24, 2006

like this one. made me laugh, and say Doh
Dec 01, 2006


nice one, shoud've thought of that

Mar 26, 2007

Wow...the most logical answer is the one I couldn't think of . To me it was obvious that the door to the magnifying glass room would've been burned already, so he would know which it was. Then he would lure the fire-breathing dragon into the other room where it would burn to a mini-crisp and the unlucky man would be home free.
May 17, 2007

This one was really fun, but very simple. The author probably should have added a few more doors to make it a little more difficult.
(I could've defeated the fire-breathing dragon, by the way.)
May 26, 2007

My mind went right to the answer. Rarely do I get the chance to say that. Sometimes I think we over anylyze things and look at these teasers as if they are science projects
May 26, 2007

Good teaser logic I didn't get it
May 26, 2007

very good teaser...... took me a few minutes, then it came to mind.
May 26, 2007

thumbs up on this little brain sqeezer...
May 26, 2007

I was tinking a long the same lines as a lot of other people.. open both doors and hope the ragon wanders into the lass room and exit through the second door! A bit blinded by the simplicity of the answer! Great job!!
May 26, 2007

Sorry for the awful spelling.. not quite used to typing on my laptop yet..
May 26, 2007

I've never been acused of being very logical but, boy am I stupid!!
May 26, 2007

can't spell either
May 26, 2007

I liked that one, but I think the answer should be he broke the glass in haif then put ut back together and made a hole, and then he climbed out of the hole. But anyway I really liked that one!
May 26, 2007

I thought it was a good teaser. It wasn't that easy. My husband, two children and I could not figure it out. It was fun to try and figure it out though.

Thanks for the chuckle. Keep these types of teasers coming.
May 26, 2007

That was so easy it was hard.
May 26, 2007

hahaaa havent read one as good as this in a while. nice one.
May 26, 2007

Got me. My logic deserted me. Good one, I loved it. Thanks.
May 26, 2007

That's easy... You break the magnifying glass!

(Yeah, I'm about the dumbest smart person ever. Fun teaser!)
May 26, 2007

You couldn't break the magnifying glass the room was all glass. I don't think U could break them all befre becoming burnt bbq or ashes. My opinion.

Loved it , the answer made me laugh at myself. Won't even mention my ideas most were in one comment or another.

Excellent & intriquing. Do More like this.
May 26, 2007

Doehead, ?????????????????

Cheer up.
May 26, 2007

a great teaser! keep 'em comin'!

btw, i got it right and I could have slayed the dragon, too
May 26, 2007

The firebreathing dragon might be asleep by that time too
May 26, 2007

loved it! i didnt get it right though...
May 26, 2007

I also thought about trying to lure the dragon into the 1st room and let him fry. So simple but...guess that makes me simple, too.
May 26, 2007

I heard this one before so I got it. I can't wait until doehead has enough points to submit teasers and quizzes . I'm sure we'll all be astounded at her super intellegence.
May 26, 2007

This one made me feel like such a dope! doh! Good one!
May 26, 2007

Excellent! Not too hard & not too easy. Just right for us who are not members of MENSA like Lmurray and Doehead appear to be.

May 26, 2007

I remember reading this one before. I thought it was brilliant then, and I still do now.
May 26, 2007

Boy I was way off, I thought if he felt the door, the one wth the magnifing glass would be hot all day and t he other just when the dragon shoot off his fire. too many cartoos I guess. GREAT WONDERFUL teaser. I loved it.
May 26, 2007

Great one!!! Loved it!!!
May 26, 2007

What you can also do is wear like tinfoil and go into the room with the magnifing glass.
But that is to say that you carry tinfoil with you for no reason. I loved the teaser it was funny.
May 26, 2007

May 26, 2007

I must join the league of the dragon fryers! It was the only thing that popped into my head. It seemed so simple, to just let the dragon wander into the other room, until I read the answer and then thought "oh, or you could do that too" and sat here laughing!! Thanks for the chuckle!!!
May 26, 2007

ha i get it
May 26, 2007

LOL, it loved that it was cute
May 26, 2007

Great teaser! My first guess was, like many others, to lead the dragon into the room with the magnifying glass... except I had the twist of crawling under the dragon while it was frying to avoid the magnifying glass! I love the answer though - so simple!
May 26, 2007

that is a good one hehe.
May 26, 2007

May 28, 2007

thats was simply cute.
Jun 11, 2007

That was awesome!! At first I did wonder if I could lure the dragon to the magnifying room, I instead decided to let the sleeping dragon lie ... and yes, I thought to go through at nighttime. I did worry that the doors would squeak when I opened them to check which room had the dragon, but I tried to be very careful....

And I think I know how the man got in the room in the first place.... he got dropped in through a hole in the roof, Probably by the dragon, which I tend to picture being the winged kind, not the chinese kind.
Mar 02, 2008

I thought that he would just wait till the dragon was asleep and sneak out. And in response to fishmed he could have been dropped in from above.
Jan 06, 2009

Pretty simple. The only thing that threw me for a moment is that this teaser is in the wrong category. This is clearly a Situation teaser.
(user deleted)
Jun 28, 2009

good one :-)
I thought of going to the door and dragon will follow me, open the door will burn the dragon and I can happily out by second door as dragon is killed.
(user deleted)
Feb 05, 2010

shalabhms, I thought the same. The information provided stated nothing about the sun's ability to move.
May 26, 2010

nice teaser .. i like how lmurray and Doehead havent even commented and people are paying them out.. hahaha.. just like evil Russell on Survivor - they think they are great and everyone finds them obnoxious..ahhh i love being on the sane side of that....
May 26, 2010

The problem when you introduce something completely illogical into a logic problem, the whole problem becomes moot and any answer is now valid. Saying there is a fire breathing dragon introduces a new variable which doesn't exist in reality. Once that is done, without defining any further rules of that new reality, people are free to add their own properties (I.e. Dragons would never hurt humans, the sun would never set) and they would be right as logic has already been dismissed in the original problem.
May 26, 2010

This was a pathetic teaser. And bear1 or whatever you call yourself,I don't think I'm smart,but if you think that I'm obnoxious don't look in a mirror or you will see the real obnoxious person.
May 26, 2010

Sorry ,I stated that wrong. I'm smart,but I don't think I'm great.
May 26, 2010

I still remembered this one from years ago. still think it's fun and I still Love this place. Just tell yourself whatever you need to hear to make yourself feel better
May 26, 2010

I was all for opening both doors, tossing a dragon treat into the glass room and hoping the dragon would follow! This one made me laugh...great job!
May 26, 2010

wow! I didn't even think about that answer! That is a really good one!
Whoever made that up has a really clever mind!
May 26, 2010

Its a fire breathing dragon, but will it breath fire on you? You go in and befriend the dragon. then u fly away!
May 26, 2010

Oh well duh! Ugh i feel so dumb!
May 27, 2010

um...sorry Doehead, but i was summarising what i have read in other peoples feedback. i can only go by that.. Please dont bully from behind the keyboard. I was having a joke..see my laughy faces..i was having a joke. i am a person that read the feedback from heaps of random people. If you read that feedback too, then you will see that i am not the only person who has found offense in comments made by you and lmurray over the years... At no point did i suggest lack of intelligence on your part. I just detect lack of integrity and empathy - different to intelligent but very very important qualities to have. Smart is just one box to tick on the personality chart. ..and dont get me started on the personal message sent to me with the angry faces...i was LAUGHING..take the joke. We can be friends here and enjoy the common love of teasers.
Jun 01, 2010

in the north pole in the summer the sun never sets therefore this wouldnt work so you should specify location -- just kidding!
May 26, 2013

Another room teaser. These are so old. I am surprised more people did not know this one. Oh well, glad you all enjoyed it. Happy holiday! A salute to our armed forces and remember the ones sadly gone and the ones here today. We are proud of them all!
May 26, 2013

I was also of the two door school of thought-enjoyed the simplicity of the answer-very zein
May 26, 2013

*zen* (fingers type on regardless of what I tell them )
May 26, 2013

I thought this was very easy. Seen these kind before. Thanks BABE for remembering us veterans.
May 26, 2013

I also thought of frying the dragon first but hen couldn't work out the logistics of leading him into the glass room. Then came up with the idea of letting the dragon fall asleep. That lead me to the wait until it is night solution.
Yes the teaser is flawed as pointed out in above comments, but it is just a teaser, meant to be fun.
May 26, 2013

I got it right away this time.
May 26, 2013

I thought about leading the dragon to the door too, then stepping to the side and let it run towards the door. I though getting even close to the door would burn it.
May 28, 2013

I pictured the doors being directly apart from each other - and like many others would open both doors (like police detective shows, kick the door open while standing to the side out of harms way.) open the magnifying one first then the dragon one and hope he runs straight across and gets fried. Nice teaser
May 02, 2016

Great simple solution, feel so stupid. My solution was to wrap himself in aluminum foil and go through the first
May 26, 2016

Of course, one presumes, though it isn't explicitly stated, that the magnifying-glass room has a door that allows the man to exit the room before sunrise.
Apr 20, 2017

I thought the answer would have been that he would go through the second door because dragons never existed so he could escape with no problem.
