Via the BB Submitterator, Liz Ditz says,
Dr. Jan Gurley (shown at left) has been going to Haiti since the earthquake, and is there now. She and friends made a video that shows you how to make Oral Rehydration Therapy (ORT) in the sheet camps, using salt, sugar, and bottlecaps to measure. 4 caps sugar, 1 cap salt, 500ml clean water = life. Direct link to video here. Doc Gurley hopes the video will go viral, aid workers have smart phones that can show videos & many Haitians have video-enabled cell phones. More at Doc Gurley's blog.
