gg anyways I bought random metals from a home depot, put them in HCl, and hypothesized which ones would be gone first, in order ofc. | ||

hahaha, yours shouldn't be so eh... explosive as ours was. we just used really fine aluminium powder, usually you put it in a ceramic pot and molten iron shoots out the bottom through the little hole. edit: i could also give you a good place to buy the shit to make it, just pm me | ||

But as far as science fair. Physics > Chem >>Biology imo. | ||

well the whole saturated solution sounds very easy and explaining the chemical reactions would be easy as well. I wouldn't recommend anything too elaborate because there will be more issues that you may not be aware of... Best of Lucks! | ||

Specifically I used a bacterium called Clostridium acetobutylicum last year to create butanol fuels. The growth media are relatively easy to acquire (some kind of sugar solution + beef extract + yeast extract + deionized water) and analysis wise you pretty much just need a mass spectrometer/Gas chromatographer. The latter may be a bit tricky to get (as they are FUCKING EXPENSIVE) but you can usually go to some college and borrow theirs. At least that's what I did. Then you just analyze results and say oh so and so bacteria >>> yeast ethanol, butanol is a good fuel, or vice versa. Material wise the bacteria is about 30$ and the other crap about 20$. I used Carolina Biological Supply Company (they have awesome service, etc.) but you probably have a Western version of it. I did that and got to be finalist at my state science fair and got $150. Go figure. If you decide to pursue this line of project I can help you out a little bit, but college will keep me busy so I may not be able to be there all the time... lol. Its Biology, Chemistry, and OChem, which is fucking hardcore. | ||

I'm pretty sure even if it was neutral I wouldn't drink it due to impurities... and if you're a little off, it won't kill you, but it will probably taste terrible. | ||

Make a device to measure changes in earth's magnetic field: http://www.all-science-fair-projects.com/science_fair_projects/7/62/e2201d694a1199ad282084665caa9698.html or make your own parabolic dish. To be perfectly honest I just dunno if the latter one is too easy to be considered for your project, but the magnetic field one is solid gold, I did very well with it. I didn't use that specific design though, so search around for something better | ||

You could hypothesize that if you put a compass on the ground that the needle would be inaccurate by X% depending on the amount of metal under the ground. | ||

one kid who went to the national level at my school did an experiment to see whether mushrooms could facilitate habitat repair or something along those lines i don't recommend doing just a random demonstration. i would try to come up with a question and an experiment rather than blowing something up, as much fun as that is  | ||

You could hypothesize that if you put a compass on the ground that the needle would be inaccurate by X% depending on the amount of metal under the ground. It's not going to be metal under the ground though usually- Compasses are usually off by a little because the magnetic north doesn't exactly match up with polar north. | ||

Resolved Question What would the reaction of francium and water look like? Best Answer - Chosen by Voters It would look like wet francium. http://www.bestofgooglevideo.com/video.php?video=327 | ||
