This invention will "enable anyone to get water from deep wells without electricity or to pump volumes of water from shallow wells. In just a few minutes of pumping daily into an overhead storage tank, an entire household’s water needs can be met, enough for watering livestock and irrigating gardens."
Gonna try this one!!! Mosquito trap - No more mosquitoes!! Cut the top off a 2 liter bottle. Invert the cone and place it inside the straight part of the bottle. Glue the two pieces together. Add 1 tsp yeast and 1/2 cup sugar to some luke warm water, and pour the mixture into the bottle. Mosquitoes are attracted to the carbon dioxide that you exhale. The yeast feeds off the sugar and emits the same gas, so the mosquito enters the bottle, thinking she will find food there.
