I recall being a kid of 5-6, and my folks wouldn’t allow us
to have fireworks. It was the 5th of July that was my favorite day of the
year – I grabbed my “briefcase” that looked like a small
suitcase and would set out for my block. I’d pick up all spent fireworks
and admire the smell. Ah!

But I had an interesting thing happen: someone driving by stopped to ask if I
was running away from home. I explained what I was doing, and they didn’t
believe me until I showed them my case full of burnt fireworks. They
laughed as the pulled away. It was then that I decided I’d stop collecting them; and started working my parents to buy the real thing. I
think that next year we got some sparklers…

for years, but it’s fun to make your own browser fireworks.
