Why is water so important?
+ --
H2O
What temperature does water boil at?
Is heat absorbed or released when you boil water?
What’s a WAPI?
Water Pasteurization Indicator
Simple thermometer that shows when water is pasteurized
Soy wax melts at pasteurization temperature
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
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
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
Today you’ll help save lives by making WAPIs!
