make 4 gallons

[cimi4749]

Hey im at work and a co-worker and I are going nuts trying to remember how to do this... we actually were filling up a few spas in our boring little world of pool and spa supplies...

well if you remember seing die hard three there was a scene where sammy and bruce had to make exactly 4 gallons of water using only a 3 and a 5 gallon container... This is driving me nuts..
The only way I can think of doing it is:
1. fill up 5 gallon drum

2. fill up 3 gallon withwut is in the five... leaving two left in the five..

3. dump out the 3 gallon and pour the two gallons remaining in the 5 into it... and then marking the jug..

4. pour the 2 gallons back into the 5.

5. refill the 3 gallon up to the two gallon mark and pour it into the
5... presto.. 4 gallons..

my co-worker happens to think that they accomplished this without making any sort of marks on the bottle...

Fill up the 3 gallon jug.
Pour it into the 5 gallon jug.
Refill the 3 gallon jug
Pour it also in the 5 gallon jug, when the 5 gallon jug is full, that will leave exactly 1 gallon left in the 3 gallon jug.
Pour out the 5 gallon jug
Pour whats left in the 3 gallon jug (exactly one gallon) into the now empty 5 gallon jug.
Refill the 3 gallon jug.
Pour the 3 gallon jug into the 5 gallon jug, and now its contents is exactly 4 gallons!

1. fill up the 5 gallon
2. fill up the 3 gallon jug from the 5 leaving 2 gallons in the 5 gallon jug.
3. dump out the 3 gallon jug dump the gallons of water out of the 5 gallon jug in to the 3 gallon jug.
4. fill up the five gallong jug again dump dump 1 gallon in to the 3 gallon jug already containing 2 gallons leaving 4 gallons in the 5 gallon jug

Go to the store. Buy 4 gallon jugs of water. Pour them in the five gallon bucket. Sit on the 3 gallon bucket and laugh at all the poor slobs trying to figure this out the hard way.
