• • Clean jar
• • Dirty jar or bucket
• • Plastic wrap
• • Rubber band or tape
• • Dirty water
• • A few handsize rocks

The clean jar should be small enough to fit inside the dirty jar.

The rubber band should fit around the mouth of the dirty jar or you can just use tape.

You'll want to start in the morning, so the sun has plenty of time to do its work.

Put “dirty” water into your dirty jar. Use creek water, river water, rain water. The dirtier the better.

You could also add a bit of dirt to tap water if none is nearby.

We're going to extract clean water from the dirty water using the power of the sun.

Our clean jar is going to catch our clean water, so we need to place our clean jar inside our dirty jar. 

The dirty water should not flow into the clean jar. Pour out any excess water to prevent this from happening. You may want to place a rock inside your clean jar to hold it in place.

Cover the top of your dirty jar with plastic wrap, and secure it with a rubber band or tape.

It needs to form a good seal around the rim - strong enough to hold a few small rocks.

Now place a few small rocks on top of the plastic wrap.

They should be enough to weigh the plastic down, but not enough for the plastic to slide off.

We want to create a slight dip in the plastic right above our clean jar.

Place your Solar Still on a flat surface in the sun, and leave it alone for a few hours.

Clean water will begin to separate from the dirty by evaporating up with the sun.

Our plastic wrap will then catch the clean water at the top and create condensation.

That condensation will then trickle down to the center due to the weight of our rocks until it eventually falls in our clean jar.

After a few hours, you'll have a nice glass of clean water.
