while (challenge them to rub them until they burst into flames).  It
always gets them that their hands smell like burning matches after
rubbing them together.  This way, you are using one more sense to get

It's also fun to look at their faces when they smell them.  (The guilty
pleasures of science demonstrations aye?)
