This is something I did a while ago but the water was quite cloudy when i finished so I thought i would have another go.
Basically get a plastic bottle and filled it with grass, sand and charcoal as densely packed as possible.
Pour the water through several times and hopefull it will get cleaner everytime. Finish it off by pouring it through a densly woven fabric like denim or windproof cotton.Then boil it to make sure all the microscopic buggers are dead. Drink!!
