Springâs warmer temperatures coax sugar maple trees to turn stored starch back into sugar. Sap is made as the tree mixes ground water with the sugar. The sap is mostly crystal clear water with about 2% sugar. It takes 40 gallons of sap to make each gallon of maple syrup which has a sugar content of 66.9%.A typical sugaring season lasts 4 to 6 weeks.he sap is mostly crystal clear water with about 2% sugar.

Oxygen is the third most abundant element in the Universe today, and in the very, very far future, may even have the opportunity to rise further as hydrogen (and then possibly helium) falls from its perch.
Oxygen has seventeen known isotopes with atomic masses ranging from 12.03 u to 28.06 u. Three are stable, 16O, 17O, and 18O, of which 16O is the most abundant (over 99.7%). The radioisotopes all have half-lives of less than three minutes.
