Two men found a whole bag of sand gold (its not solid) treasure in the desert. Time came when they had to split thier ways and devide this whole bag. However, they dont have any kind of measuring equipment/tool. Nothing. Just 2 bags. (of course, one is full with sand gold)
How can they split it fairly so both parties agree on it and are happy about the split.

One will be in charge of splitting it in two portions, and the other will get to decide which portion he wants to keep. This will insure that the one in charge of splitting portions will do it as evenly as possible
OR
they left the bag behind. that way it was split perfectly
