Ever wonder why jelly and Maple Syrup keep (fail to spoil) without adding a chemical preservative?

Sugar is a preservative so long as it is added so the dissolved solids equal 65.5 percent. I don't understand all of the chemistry surrounding it but I'm told that sugar kills organisms via osmosis (movement from a lower density {from the bodies of organisms} to a higher density {the sugar solution}).
