Breathe easier on smoky days

Image
The same mask that stops colds and flu in the winter can help you breathe easier when forest fires are filling our air with smoke.  Your breath moistens the inside of the mask; smoke particles get caught up in the moist cloth, greatly reducing the amount you take into your lungs.  A bandanna cold mask has more cloth to catch the smoke than a dust mask or medical mask, and more room inside it to breathe easily.           You can breathe easier in your yard by using misters to clear the smoke by taking it to the ground, where it becomes good fertilizer.  The snakelike standing plastic misters with twin emitters that you can usually buy at the Grange Coop or Diamond Building Supply work very well for this, as they produce a very fine mist.  They also can be moved around, as they are made to be used on a hose.  (The hose should be heavy duty 5/8” or cheap ½” to take the pressure.)  Individual mist emitters tha...

Keep food and drink cool with water

You can keep food and drinks cool on a camping trip or in an emergency without ice or a refrigerator, using the powerful cooling ability of water, which evaporates at 41 degrees, and therefore can cool stuff to 41 degrees, regardless of air temperature, as long as relative humidity is not 100%. Take a jug of water.  Put it in a shallow pan.  Cover it with a towel, and let the ends of the towel lie in the pan.  Pour water over the towel and fill the pan.  The water evaporates from the towel, which wicks more water from the pan, cooling the towel and the mass of water beneath it eventually to 41 degrees F, the point below which water stops evaporating.   Theoretically, one could cool a box of food by setting it in a bigger box and covering it with a wet towel that lies in water in the larger box.  I cool and keep grapes and melon slices fresh, moist and free of flies by covering their bowl with a wet towel set in a shallow pan of water.
