We spoke on the phone to an Irish girl, Elaine Bannon, on Saturday who is in Kenya (she is in the bush near the Equator) working with the Masasai warriors.
She has received a consignment of personal LifeStraws via Brynmawr W P. One way she uses them is to demonstrate them, suggest that they can be used when they follow their cattle.
However they only get one if they promise not to carry out "Female Circumcision" on their daughters. a very unusual use of life straws. Visit their website and read about their work: www.lightofmaasai.com
