Water Purification Methods
1. Solar Disinfection (SODIS)
Materials: glass or PET bottle, piece of cloth
How:
 - Filter off larger dissolved matter from water using cloth filter.
 - Fill bottle with water and leave bottle in sun for 12 hours. UV rays will kill all bacteria in bottle
Note: this method is the simplest but does not remove dissolved harmful chemicals

2. Solar Powered Distillation
Materials: black painted bottle with long capillary tube attached to cap; collection bottle
How:
 - Fill bottle with water. Black paint increase heat absorption.
 - Place bottle on platform under the sun so that it is higher than collection bottle
 - Place capillary tube and collection bottle under shade (to help with steam condensation)
