|Molecular Diagram of liquid water (oxygen atoms are red, hydrogen atoms are gray): Note the lack of open space and the dense structure|
|Molecular Diagram of solid water (ice): Note the open space and repeating structure, called a lattice (source at bottom of page). This structure makes ice less dense than liquid water|
This property of ice expanding also can been seen in more mundane ways - put a soda (which is mostly water) in the freezer and it will soon explode, making a sticky mess.
How does all this related to the Groasis Waterboxx? The Waterboxx works by collecting dew and rainwater usually a specially designed lid designed to mimic the action of a lotus leaf. This water is funneled into a basin that hold approximately 4 gallons. Since the Waterboxx refills from the sources listed above without any human intervention, it is always full of water. This is why it helps trees survive dry periods and develop deep roots. However, a rational concern would be this - will the water freezing in the Waterboxx in the winter cause the Waterboxx to burst, ruining your investment? The answer is no. The Waterboxx was designed with up-sloping sides, allowing the more voluminous ice to push upwards. There is empty space between the lid and water the allows free movement of the ice. The lid is firmly in place but not permanently attached, and the worst that can happen with the water freezing is the lid being displaced. In this case, the lid will need to be replaced in the spring. The Waterboxx cost 7.1 million dollars and took 7 years to develop, being tested in the world's most extreme environments, all with success. In the Sahara, 88% percent of seedlings survived using the Waterboxx, versus 11% without the Waterboxx but with weekly watering. The Waterboxx helps insulate the trees from drying winter winds.
