Instructions
Fill a large, clear bowl just less than halfway with water.
Add impurities to the water. You can use items you have on hand as an impurity, such as vinegar or salt. Alternatively you can also use turmeric, curry powder or food coloring as an impurity. Log what you add to the water in a journal along with the date and time you added it.
Test the water's acidity using pH paper. Log the water's acidity in a journal along with the date and time you tested it. Testing with pH paper only works if you've added vinegar or something acidic to the water.
Position the empty drinking glass in the center of the bowl with the top part of the glass facing upward. Make sure the water doesn't flow into the drinking glass when you put it in the water.
Cover the bowl loosely with cling wrap.
Put a pebble or other small weight in the middle of the cling wrap. The cling wrap should sag toward the top of the glass without going into the glass. If the cling wrap is too tight or too loose the clean water may not be collected properly.
Leave your distiller out in the sun for a couple of hours. You should find the glass has collected clean water and the impurities have been left behind. Test the water's acidity with pH paper. Log the results of your acid test along with the date and time.
