I love science as well as all the options and future discoveries just waiting for someone to discover. While doing some research online for a project, I came across an ad that said you could run a car on water. And, believe it or not, this is apparently true. If this can happen, what could happen next? I think the possibilities for powering cars and other items could be endless. How great will this be? Use water, which is cheap, to help power your vehicle. If I could save money on the purchase of gas for my car each week, then I would be ecstatic.
