It is a good idea to treat all fine powders as hazardous. After all,
we're designed to breathe nitrogen with a few other gaseous impurities.
If you breathe enough of something else, no matter what it is (cotton,
coal, gypsum, copper, lead, silica, soot, asbestos, talcum powder), you
can count on trouble.

On the other hand, don't let that scare you or your niece off what
sounds like a thought-provoking science project. Instead, plan not to
ingest the nickel. Wear a dust-mask, safety glasses, and gloves while
mixing the powder into the soil. Moisten the soil before hand so that
the powder does not become airborne during the mixing. Discard the
masks and gloves and wash your hands when you're done.

Have fun,
