What is a good science fair project?
in school we have science fair and i need to come up with a project. I like mechanical things not growing plants or anything like that. one year i did centrifugal force then another on the otto cycle but never got in :(...i have to use the scientific method, i was thinking something along the lines of how different nitro rc fuel percentages effect nitro engine preformance but thats kinda obvious and lame. i was also thinking of making a stirling engine but dont know how to fit the scientific method into it plus i never got any of my engines to work :( Just let me know if you guys have any good projects i can do? like i said im mechanical but i dont really have any tools to make stuff.
