Distilled Water

Needed:
Tarp
can
From campsite: one pebble, leaves, sand or rocks, and a hot day.

Dig a hole and and place the can in it. Put leaves around the can. Place the tarp over the hole. Put rocks or sand around the tarp so the can is enclosed. Place the pebble over the can (so the water can drip down). Wait a while and get your water!
