Hi Jennie-

I don't know anything about phenyl oxalate ester but I can offer you the
crunching wintergreen lifesavers trick that will produce a spark in your
mouth that can be seen in a darkened room. I'm not sure if that's big
enough for what your students want.

Our recent Candy webcast site offers more information on the trick:

Good luck,
