The Die Hard Water Riddle Explained by a Unicorn by PixelKitties The Die Hard Water Riddle Explained by a Unicorn by PixelKitties
Tonight we'll be watching Die Hard With A Vengeance, aka Die Hard 3 in the stream. In honor of the occasion, here's a quick synopsis of the water jug test that villain Simon forces our heroes to solve under threat of exploding.

When I was a kid and I first saw Die Hard 3, I was frustrated by my pea-brains inability to suss out how exactly this things worked. Only as a grown up with a velociraptor sized brain did the answer finally sink in.

Thanks a million to :iconevilbob0: for the chalkboard vector!

I don't think I've even heard of this sort of thing since, like, third grade

I love the Die Hard Series.

You having a nice day, miss?
You feeling alright?
Not to get too personal, but a purple alicorn in Cloudsdale, wearing a sign that says "I hate pegasi", has either got serious personal issues, or not all her dogs are barking.

I think muse magazine had explained this one many years ago too.

Shouldn't you just pour one gallon out of the five gallon jug?
watergod159 Featured By Owner May 24, 2014
The gallons are not marked individually and if you put any more or less then four gallons on the scale, then it explodes, this is the fastest way to get the challenge done

Meanwhile the bomb goes off while you're dicking around with the jugs and dozens of ponies are killed.  Several more are injured, and the mangled corpses and severed limbs leave an entire city horrifically traumatized, ultimately culminated in one pony going completely insane, taking up drinking blood and summoning the Wendigos again, ending in the Equan's extinction.  All because you didn't just telekinetically pull the green wire.

Raven: Which would've set off the bomb anyways, and you should've cut the red wire instead.

There's an alternative solution to this problem:
-Fill the 3 gallon jar and pour it into the 5 gallon jar.
-Fill the 3 gallon jar again and pour 2 gallons into the remaining 5 gallon jar space.
-You have one gallon in the 3 gallon jar now. Empty the 5 gallon jar.
-Pour that one gallon into the 5 gallon jar. Refill the 3 gallon jar.
-Pour all three gallons from the 3 gallon jar into the 5 gallon jar, adding them to the one gallon that's already there.
-You have 4 gallons in the 5 gallon jar.

Perfect.... and I would say the more correct way to do this (since they are not marked in any way).  ^_^  (y)

Hahaha ! Great idea !

Thank you Twilight !
KingArthur5 Featured By Owner May 6, 2013
I keep trying to remember the answer. I figure it out every time, but I forget how to do it every time... But now, with Twilight Sparkle's demonstration, I will never forget! Thank you science!

This is a better Die Hard than Die Hard 5

Quick! Add her in human form to the Die Hard cast! :D

Fabulous, scientific education, you can't beat it, can you?

I learned this in 8th grade when we were doing challenges that test your mind.

I always wondered about that, cause they speak so fast in the movies, it's always like, "Wait, What!? Can you repeat that?"
ZeldaAdlez Featured By Owner Feb 19, 2013
Or simply fill both jugs, pour out half from each, and pour remainder from 3 gallon jug into 5 gallon jug.
supercj1 Featured By Owner Feb 25, 2013
you never saw Die Hard with Vengance, it had to be EXACT or it would blow.
Evilbob0 Featured By Owner Apr 25, 2013
I like ZeldaAldez's answer! And it should work anyhow.

If you're arguing that it had to be more exact than that; the method used in the movie probably wouldn't work either.

If you ever took a science lab course, you would know that error for each of those jugs, as measuring implements not designed for exact science, is pretty high. Moreover, each iteration of pouring back and forth would only have compounded the error (due to water tension, spilling drops as it splashes out, etc.).

That is not even taking account that "Exactly four gallons of water weight" does not necessarily take into account the mass of the container, barometric pressure, distance from the center of the Earth this measuring shenanigan is taking place, etc., etc.

QED It isn't as exact as you claim it to be, and I don't see why ZeldaAldez's answer wouldn't work just as well!

And then explode cause you were off a milliliter. XD

that's way too simple, where does the moose and helicopter come into play?
Centaur71 Featured By Owner Feb 10, 2013
Why not just fill the 5 gallon jug...and pour one gallon off?
Frosty-137 Featured By Owner Feb 10, 2013
In the movie, the bomb required it to be exactly 4 gallons, if they were off by too much, the bomb would blow up. Trying to estimate the amount to remove would be too risky.
DemonPanther Featured By Owner Feb 10, 2013
In WoW, I have to do math like this a lot.
Reforging is a pain in the flank, but it helps maximize your effectiveness
uzqap Featured By Owner Feb 9, 2013
i wonder if it had been posted before but there is a second way of solving this.

fill the 3G jug - pour 3G into the 5G jug - fill the 3G jug - pour 2G into the 5G jug - 1G remaining in the 3Gjug - empty the 5G jug - pour 1G +3G into the 5G jug to have 4G

first time i saw that movie i had to pause the VHS to solve this...

goddam i'm old...

I'm gonna be honest, this took me about 30 seconds (without reading the comic) after I saw the 5 and 3 gallon jugs...

Lucio1995 Featured By Owner Feb 8, 2013
If you can just "calculate" how much is a gallon in the 5 gallon jug, you can just start by putting 1 gallon in the 3 gallon jug.
SchwarzerRitter Featured By Owner Feb 11, 2013
You can't "calculate" one gallon.
The 3 gallon jug had room for 1 gallon left.
