In each workshop children participate along with their mothers, and in some communities fathers are starting to participate too. Starting out with the CooKit, because it’s the simplest and cheapest type of solar cooker, we explain the why’s and how’s of solar cooking, demonstrate the cooking of various sample foods and the purification of water with a WAPI, then help each family to construct their own cooker. Two to three weeks after a workshop, I do follow-up visits to see how the women are doing and help with any problems.
