Simple Vices #2 Sperkin'

This must be one of the most obscure childhood pastimes ever.

Invented by Arkos, Sperkin' was a practice of detonating roll caps with your thumb nail and inhaling the resulting smoke. The idea being that you could get enough smoke in your mouth to blow a smoke ring.

There were the inevitable burns to the tips of your thumb and the nail would have a whitish/ yellowish deposit of saltpeter and singed nail.

To get the smoke you had to fire the cap directly into your mouth.

As you can see the box clearly says "do not fire closer than one foot to the ear".

I used to be pretty good at Sperkin', wouldnae mind another shot at it.
