" Failed Unknown Reason" me been trying to up load this for 3 hours! had to remove all the kats talking instructions to finally upload. click green flag to start. first rub the plastic comb on the piece of wool cloth. Next touch the static charged comb to the top of the jar and the purple spot. The jar will get a static electrical charge causing the two pieces of foil inside the jar to repel from each other. move scratch up to top and he will discharge the jar allowing the two pieces of foil to hang down and loose their electrical charge.
