Welcome
We have to make some toy thing in physics that has a moving part or something in order to relate it to the laws of motion, so while most people are doing rubber band-powered cars or something, I'm thinking of just bringing in an eggbeater or maybe even a lawnmower. Just to show that my projects can be made with quality - hopefully no one will wonder if I actually made them myself. But then she said that the motion could be started by a force we apply to it or something, so now I'm thinking of bringing a baseball and throwing it at someone. And apparently I might be part of a couple staged fights during class later this year, so we'll have to find someone else to record the videos.
