Copper Rails
Ideas for a power project or sound?

I have a demonstration project for my class tomorrow for Physics 2. After have tried a gun Ionocraft rail and I'm running out of ideas. I copper wire, ohmmeter, and the possibility obtain any other single material. Please help me.

OK, do not panic! I do not have much time to keep things simple but unique. If you can buy or build a simple audio amplifier with a gain of, say, 50 years, there may hope. Build and demonstrate a simple audio monitor based in the heart. Go to Radio Shack and buy a piezoelectric transducer, P / N 273-073A for about $ 1.99 each. Carefully remove the plastic casing around the probe and compile it into another type of plastic housing so that the elements of a probe is aligned with the housing. This is necessary for the element to be pressed against his chest. A bottle cap pill works. Connect a cable (two son) between the sensor and amplifier. The best results can be achieved when the sound comes from a small speaker, but the headset works well too. The sound quality of the heartbeat that unravels heard by a doctor. Good Luck stethoscope.
