Where there is charge, there can be sparks

Hello, my 10 year old son has chosen "where there is charge, there can be sparks" science experiment from the science buddies web site. We have been trying for about a week to do the first step and are having no luck in the first step. I am literally having bad dreams about this, because we already told the teacher that this is the project we chose for science fair, and it's too late to change. We first assembled the electrophorus (aluminum pie pan,scotch tape, and styrofoam cup),now we try to charge the electrophorus by rubbing an acrylic sheet with wool for 15-30 seconds and we get nothing. We hear a little bit of static forming when we rub the sheet with wool, but not much. We pick up the electrophorus by holding the styrofoam cup and set it on the acrylic sheet and.... Nothing . So of course when we try to charge the Leyden jar we also get... Nothing.we have followed all the directions, multiple times and still nothing. Do you have any suggestions on what we might be doing wrong? Have any other kids done this experiment? Any help is greatly appreciated. This project has taken over my subconscious .
