Yep
APP Stiyx are be quite useful. Just not sure .... for what
Although I suppose one could lay them end to end down the driveway and set one end alight and time the flame propagation to the other end?? Or lay them out in a circle and set one side alight and see how long it takes to get to the other side of the circle. Or set them up on the porch and every time some tiny creetin rings the bell to say "Trix or Treats" set one alight and see how fast the little nuisances can run for the street.
Just some applicable thoughts.
Nothing special.
Nor actually appropriate.
If you had a non-metallic mortar and pestle you could return the styx to powder form.
Or not.
