first fill the 3 gallon jug completely and then fill the five gallon jug till the 1 gallon marking which is printed on the jug. In today's world we do get marked jugs and so by doing this you will get exact 4 gallons water.
But I guess Ben is right. Good going Ben.

Fill up the five gallon jug, pour the water in the five gallon jug in the three gallon jug... When you fill that jug up, the left over water in the five gallon jug is two gallons. Pour out half the water in the five gallon now. Therefore, you have four gallons. One gallon in the five gallon jug & three gallons in the three gallon jug...
~~~~~~~~~~~~~~~~~~~~~~
Or, break a long twig to measure to the top of the five gallon jug. Then break off another peice of the twig to measure to the top of the three gallon twig. Save the two peices you break. Then, fill the three gallon jug up & break the shorter portion of the twig in half... throw away one of twigs with the same length as the other. Then, put the shortest twig up to the five gallon jug and fill the five gallon jug to measure the length of the twig with the twig still sitting up beside it. That would be one gallon, & in the three gallon jug is three gallons, so both of the jugs gallons added together is four gallons!

Fill the 3-gallon jug half-way (that gives a 1.5-gallon of water), then fill the 5-gallon jug half-way (that gives a 2.5-gallon of water).Mix the two (1.5+2.5=4) and you get your 4 gallons.

Fill the 3 gal jug and pour it into the 5 gal jug, and then do it again. You should be left w/ one gal in the three gal jug. Then dump out the 5 gal jug. and empty the one gal into the 5 gal jug. Then add another 3 gal jug to it. Voila! 4 gallons.

Ben's way works too., damn, he was quicker!

Fill up the five gallon and pour it into the 3. You have 2 in five and the three is full. Dump out the three, pour the two from five into the three. The three is now short only one gallon. Fill the five, pour into the three (with the 2 gallons in it) untill it is full. The five will be left with four.
