  1. Why is water so important?

  2. H2O - + -

  3. What temperature does water boil at? Is heat absorbed or released when you boil water?

  4. What’s a WAPI? • Water Pasteurization Indicator • Simple thermometer that shows when water is pasteurized • Soy wax melts at pasteurization temperature

  5. What’s pasteurization? • 65°C • Disease-causing organisms in water, milk and other liquids are killed by exposure to heat and the liquid is rendered free from E. Coli, Rotaviruses, Giardia, and Hepatitis A

  6. Importance • Water doesn’t have to boil to 100°C to get rid of these bacteria (you can stop at 65°C) • People in underdeveloped countries spend a lot of their day collecting fuel and wood

  7. Importance • About 1 billion people in the world do not have access to safe drinking water • Water-related diseases are responsible for 80% of deaths in third world countries! • WAPIs can be reused

  8. Today you’ll help save lives by making WAPIs!
