Earth Batteries Dirt makes pretty good batteries. It seems like moist dirt packed tightly works the best. Add just enough water but not too much. I guess if the dirt dries up‚ you’ll have to water the batteries along with the rest of the plants. The soda can version works but I haven’t tested extensively. You don’t really have to use a penny‚ just has to be copper. Perhaps other common materials would work better. Each cell gives you a useless 0.5 volts. But if you link them in series you can

Writing ionic equations for redox reactions You can split the ionic equation into two parts‚ and look at it from the point of view of the magnesium and of the copper(II) ions separately. This shows clearly that the magnesium has lost two electrons‚ and the copper(II) ions have gained them. These two equations are described as "electron-half-equations" or "half-equations" or "ionic-half-equations" or "half-reactions" - lots of variations all meaning exactly the same thing! Any redox reaction

Paint-it-Yourself Luar Martinez April 1‚2011 Eng. 111-HB1 K.L. Thomas Do you believe that things turn out right only if you do them yourself? If yes‚ well you’re in luck‚ because today I will show u how to paint your own car. The entire activity can take about five to six hour and requires a lot of precision; but it allows you to expand your creativity and even save a couple of bucks. Before even thinking about painting a car‚ you must first have dry and dust free area(carport). Also if your
