Hey everyone, I'm a grade 11 high school student taking Physics and I'm having no trouble whatsoever :). For our final end of the year project, we are expected to come up with a physics lab/experiment that has to relate to either motion,light,sound, waves, energy, electricity or magnetics or a mix of any. The top labs/experiments will be sent to Montreal, Canada for a physics expo. I really want to get in however I need a really cool and interesting experiment to do. If you guys can provide me with ideas of some very cool experiments that are really original it would be great. Thanks in advance! Edit: I just found the science fair project ideas post however the ideas I am looking for need to be as original as possible... something that no one has ever done!!
