Don't know if this will help, hope so. My grandson (in the 6th grade) is going to help his granddad (my husband) build this for his science fair project. Last year he did water purification utilizing the SOLIS method and he won first place! (Uses 2L plastic soda bottles, black plastic and sun.)
Thanks. I'll play aound with that and see what happens after Wilma does whatever it's going to do.
