My brother-in-law gave one of my kids a Razor brand sparking scooter
last month. I've looked at the sparker thing and it appears to be a
solid block of some soft metal. It isn't as brittle as sparker flints.
It works really well at giving large trails of sparks along the
sidewalk. I'm curious what the sparker is and if it could be used for
simple home-made pyrotechnics (like sparkers from lighters can be:
pull out the "flint" heat it in a flame until glowing, the spring
from the lighter is good for holding the flint in a flame, then dash
against a hard flame-proof surface: explosion of sparks).
