I suggest,

Water Electrolysis, the directions are below on how to do it I did this once before and the teacher was amazed!!

Hydrogen is another potential source of sustainable energy, and you can easily generate some by disintegrating water into its basic elements via an electrical current. Take a large battery (9 Volts or above), connect wires to its terminals and dip them into salty water. You should see bubbles forming around the tips of the wires as the water breaks down into oxygen and hydrogen. Try using different materials for the electrodes (like nails, or the graphite from a pencil), and different additives for the water (like vinegar, or distilled water), in order to achieve a more efficient process and generate more bubbles.

I hope this helped you!!

BigCrippin: all the topics you posted were great ones! It just depends on what your interested in and all of that.

nancy215: yess

BigCrippin: So i agree with all of the ones you posted. I'm very interested in science and all the things involving all the chemical imbalances and all of those awesome things. Science is all about experiments and its a great experience to encounter!

nancy215: yess. i too like it. science is not only a subject but adventure. try exploring different things.

BigCrippin: We should interact more.? I think we have some things in common we could talk about all the awesome experiences we have had with science or that we are wishing to experience! I don't come into contact with many people that actually enjoy the experiences of science as I do..
