Which methods can be used to obtain fresh water from seawater?
The process of converting salt water to fresh water is called desalination and there is a lot of information on the subject. Mother nature turns salt water into fresh water everyday by evaporation of water from the oceans. Clouds, with water vapor, water droplets and ice crystals form from evaporation. Then, it rains or snows nearly pure water/ice. When humans artificially create pure water, the water is typically heated to drive the pure water off as water vapor and leave the salts behind. In chemistry, heating a liquid to vaporize it so that it condenses in a purer form is a process is called "distillation". Another process, more specifically for water, is reverse osmosis filtration through a series of differentially permeable membranes allowing pure water to pass while trapping salts and other impurities. When any process is used to remove salts from seawater, the process is called desalination.

How do you freeze fresh flowers for later use?
Freezing fresh flowers will destroy them. Think of any flowers you've seen after "an early frost". At best you could chill them as they are done commercially, they would need to be kept refrigerated at a temperature of about 10 degrees C - in a container filled with water. Chilling does not prolong life indefinitely, but slows down the process of deterioration. Temperatures from about 3 degrees C result in the formation of ice crystals in the cells of the plants which puncture and kill the cells.
Should boiling water be used for drip coffee?
No. The idea temperature for brewing coffee is below the boiling point. Water is best at a temperature of 195 to 205F before running it through the fresh ground beans. Always start with fresh cold water in an auto-drip machine to allow the heating element to reach its optimum brewing temperature.

Which liquids will preserve flowers the longest?
The best 'liquid' to maintain flowers in is the following: --A sugar/water solution (the ideal proportions may take some experimenting) --something that lowers the pH of the water and keeps bacteria and fungi from growing, like a biocide. Using this method can make fresh flowers last for as much as 30 days or more!
How do you keep spinach fresh?
I have found the best way to keep spinach fresh is to treat it like flowers. I put in a jug of fresh water which I change daily. You can keep it either in the refrigerator or away from direct sunlight on the kitchen bench. With that said I still try to use it as quickly as possible
