We're planning a detective-mystery-themed birthday party for Tani, and tonight we did a dry run. For part of it, I wrote with lemon juice on a piece of paper, and H went to try making it visible. From the other room, I suddenly heard her exclaim:

"These are all friggin' CFLs!"

Um, oops. We need a plan B. :-)

Toaster?

After that we started talking about other ways to do it, and it was a happy thing that being SF fans, we know the combustion temperature of paper. Eventually we found a standard bulb, and the old trick still works. Surprisingly, the hair dryer didn't.

I hear a lot of birthday parties include candles... :)

We tried it over the open flame of the stove, too, but fear of burning ourselves kept it from working. This has to be something safe to do with 10 seven-year-olds. In the end, I think we're going with another form of invisible messages: the old pencil impression left on the paper underneath bit.

Okay, I'm stumped: What are CFLs??

Compact Fluorescent Lightbulbs. Which do not get hot, and therefore do not reveal lemon-juice writing.
