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!

Shouldn't you just pour one gallon out of the five gallon jug?

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.

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)

Or simply fill both jugs, pour out half from each, and pour remainder from 3 gallon jug into 5 gallon jug.

you never saw Die Hard with Vengance, it had to be EXACT or it would blow.

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!

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.

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

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.

You can't "calculate" one gallon.
The 3 gallon jug had room for 1 gallon left.
