Science Fair Help LEYDEN JAR?

Hello All, My Daughter's 8th Grade Science Fair is approaching fast and WE NEED HELP. We Built a Leyden Jar using a 5 Gallon Bucket Covered outside with aluminum foil, filled with salt water, with a large "Heineken Keg" beer can (4" diameter) as the center electrode, and a 2" oval brass cabinet knob soldered to soft 1/4 inch copper pipe as the electrode connecting to the outside. A piece of copper pipe inserted into the center electrode is immersed in the salt water. Spark Gap spacing is about 1/4" We have kept everything as smooth as possible to reduce bleed-off points. We tried charging it by using 3 foot lengths of pvc pipe rubbed with wool socks, to no avail. When we charged it using a piece of aluminum foil taped to our 25" TV, we initially got a couple juicy sparks, but then nothing. If anything jumps out that we are doing wrong, I would appreciate input. Also any ideas about building a better static generator?? Can I use my X-wifes Barry Manalow records or should I save them for the skeet range? The Science fair is on the 30th....HELP!!! Signed Mike AKA Dad
