ydoaPs Posted December 4, 2007 Share Posted December 4, 2007 Can't you do the project on how it's a scam? A few cool ones I've seen are: 1. making sugar from carbon and water 2. using the piezoelectric effect to have a microphone power Christmas tree lights.

mikehad Posted December 4, 2007 Author Share Posted December 4, 2007 for the scam,, my teacher said to drop it.. but whats this thing with the christas lights.. Link to comment Share on other sites More sharing options...
ydoaPs Posted December 4, 2007 Share Posted December 4, 2007 Microphones take advantage of the piezoelectric effect(vibration or pressure applied to some crystals creates a voltage; an applied voltage to the crystals causes vibration). Quartz watches also use this effect. Well, this kid used the microphone to make sound powered Christmas tree lights. Link to comment Share on other sites More sharing options...
mikehad Posted December 4, 2007 Author Share Posted December 4, 2007 I need guys.. a good idea this is like 75 percent of my term mark.. PLEASE GUYS im dyin here... Link to comment Share on other sites More sharing options...
ydoaPs Posted December 4, 2007 Share Posted December 4, 2007 When's it due? Where are you at in school? If you want a easy project, the piezoelectricity is a good way to go. I'm not sure how the one kids made sugar out of carbon and water, but they went to the national science fair for it. Link to comment Share on other sites More sharing options...
mikehad Posted December 4, 2007 Author Share Posted December 4, 2007 thanks bud, so the piezo electricity is the way togo? but what can i do with the electricity made by stress.. what can come out of it?? its for in 2 days... a small pre-report sort of thing..

ydoaPs Posted December 4, 2007 Share Posted December 4, 2007 Power something electrical with it. In the case of the project I saw, it powered Christmas tree lights. Link to comment Share on other sites More sharing options...
MrSandman Posted January 9, 2008 Share Posted January 9, 2008 Take gasoline and disolve alot of styrofoam into it untill it is a paste. Becarefull not enhail the fumes. Poor the paste into a sealable container and make a fuse, say by dipping a roll of toilet paper in it. roll the toilet paper out about 30ft from the container light the toilet paper and watch the container explode. Awwww, but it looks like you must have already got one. Link to comment Share on other sites More sharing options...
plant lord Posted January 10, 2008 Share Posted January 10, 2008 well you could do a simple project/experiment that prooves vinegar to be a mild acid and prooves other things two but i am to lazy to think of any 1) get an egg, glass jar or cup,and some vinegar 2)put the egg into the cup or jar 3)fill the cup or jar with vinegar so its a little above the egg [4) oyu may want to cover the egg, i did. i am doin the eperiment rite now lol] ok so what will happen is that the vinegar will have a chemical reaction with the calcium carbonate(egg shell) thus turning the calcium carbonate into carbon dioxide (its interesting, you can see the bubbles) in about 3 days the shell will be gone hopefully you have secsesfuly peeled a raw egg i dont now if your science has gone buy yet but if it has it still would make a good experiment Link to comment Share on other sites More sharing options...
