For our water week finale, we are going to go outside in our yard and use the methods we discussed with you to make a solar still and use the condensation method on a tree branch to see which produces more water.
Practice makes perfect, so if you want to be able to make a solar still, or tell someone else how to make one, go on outside and try it. We would love to hear from you about how well yours came out.
Solar Water Still
- The basic principles are that you dig a hole 18 inches deep and about 3 feet wide.
- Put a collection bottle or cup in the center to collect the water.
- Cover the opening of the hole with a clear sheet of plastic.
- You can use rocks to hold it down.
- Make sure that the plastic forms a cone down inside the hole, so when the condensation happens it will fall into the cup.
This type of still should gather 1 pint of water or a 24 hour period.
- Tie a clear plastic bag around a branch.
- Tilt the bag so that a corner is down lower than the rest of the branch so the condensation will collect in a bottom corner.
Good luck to all those that are going to try this. As they say practice makes perfect so you might want to at least try it once before you have to make one in a real emergency survival situation.
