Question 782205: 1) In the movie, Die Hard with a Vengeance, the hero was told that in order to stop an explosion from taking place he would have to place a plastic jug with exactly four gallons of water in it on a scale. The wrong weight would set off the big bang. Unfortunately, the villain had left the hero only two jugs, one that would hold exactly 3 gallons and one that would hold exactly 5 gallons. There was a fountain nearby with lots of water in it. Explain how to get exactly four gallons into the five gallon container.
Restrictions: There is not a measuring cup available. You are not allowed to mark water levels on containers. You must have exactly four gallons - no estimating.
