I am doing the project, "How Well Do Different Materials Create Static Electricity?" The instructions say I need to use a wooden ruler? Would it be possible to use a plastic ruler?

Hi - a plastic ruler is more likely to build up its own static electricity, which will affect your measurements. It is best to use a wooden ruler if you have one available. If not, you can try a plastic ruler, but watch closely to see if the ball moves when you bring the plastic ruler close to it. If it does, then you should get a wooden ruler. Hope that helps!
