For effect, have someone hold a fluorescent tube under the lines.
I do that all the time under the 100-300KV (Don't quote me on that) lines behind my house, mainly to amaze my friends.
After this I decided I would never live under transmission lines.
Too late for me, there's ones behind me. There used to be houses at the ends of the drainage depression, but they were demolished when the 100-300KV transmission lines went up. I'd hate to live in an aluminum-sided trailer under a set of transmission lines.
