    Riddle Me This, Riddle Me That
    You have a bucket that holds 4 gallons of water and another bucket that holds 7 gallons of water. You must go the lake and bring back exactly 5 gallons. How would this be done?

    2. Put 4 gallons into 4 gallon jug from 7 gallon jug
    3. Throw away 4 gallons jug
    4. Put 3 gallons from 7 gallon jug into 4 gallon jug
    5. Put 7 gallons into 7 gallon jug
    6. Put 1 gallon into 4 gallon jug from 7 gallon jug
    7. Throw away 4 gallons from 4 gallon jug
    8. Put 4 gallons from 7 gallon jug into 4 gallon jug
    9. Throw away 4 gallons from 4 gallon jug
    10. Put 2 gallons from 7 gallon jug into 4 gallon jug
    11. Fill 7 gallon jug
    12. Put 2 gallons from 7 gallon jug into 4 gallon jug
    13. You now have 5 gallons in the 7 gallon jug.

    Fill the 7gal bucket
    With it fill the 4 gallon bucket leaving 3 gallons in the 7 gallon bucket.

    Dump the 4 gallon bucket then fill it halfway.

    5 gallons. Does that work for you? :)

    Edit: aah shucks, the monk beat me with a much more exacting answer.

    Too complicated Monkey Boy. Jeez, you scientists over think everything.

    Fill the 4 gallon bucket. Pour into 7 gallon bucket.
    Refill the 4 gallon bucket. Pour into 7 gallon bucket.
    You will be left with 1 gallon in the 4 gallon bucket. Dump the 7 gallon bucket out and pour the remaining 1 gallon into the 7 gallon bucket.
    Refill the 4 gallon bucket and pour into 7 gallon one. You now have 5 gallons in that bucket.

    Pour the 4 gallon bucket into the 7gallon 2 times- you have 1 gallon left in the 4 gallon bucket. Empty the 7 gallon bucket back into the lake. Then pour in the remaining 1 gallon in the 4 gallon bucket, and pour in another 4 gallons.
