These were composed of a material which resembled a gob of
greenish snot. They could be purchased in sheets of paper
for a "locha" and they were glued to the paper --
about ½ inch in diameter. You could activate them by
rubbing them vigorously across your jeans or any rough surface
and then throw them and they would sputter and crackle with
sparks and smoke.
Well, we had a tap
dancing class in Tia Juana (you know where I am going) and
I did not tap dance because it was for sissies. The class
used to dance on the stage at the Staff School. I used to
watch and when the mood stuck me I would peal off half dozen
of the triki-trakis and toss them out on the stage and as
the "wimps" danced their routines they could hit
the triki-trakis with their steel taps and then the dance
would pickup in tempo which did not coincide with the music.
We would also buy Chinese
fireworks which came in small packs wrapped in rice paper.
Sometimes we could get a miniature of a regular 2-inch fire
cracker and these just popped and since they were very dangerous
we would light them and toss them at each other. As we got
older, we were able to buy a very powerful firecracker similar
to a military M80. These were nothing to be careless with
as they could do major injury to a person.
