Paul,
Does your subject have to experience an ac signal or could it be dc? If
dc is okay, then you can hook the small 9v batteries together. Their true
voltage is between 9 and 10-v when they are new. With this ~10v step you
can get to the threshold in a much safer manner. If this is a good thread,
feel free to post.

I love this idea, but I dare not show it to kids. "Dead" 9v batteries are
around 8V. Any kid that can collect 8 or 10 dead batteries can connect
them directly to each other and create a lethal hi-voltage battery. 13
fresh batteries can easily supply an amp, and light a 100w 120v light bulb
to full brightness.
