Sorry Dudes,
I've actually watched the video now (I hadn't even clicked the link before).
You could say I was a little "Premature"...
I'm with Col, That_Guy, etc. It's a toy. I've made better flame units with crop sprayers / naphthalene as a kid. Nicely presented and compact.
Time to just stand back and watch the fun I think.
Post any particular accomplishments
here.
Interesting about the NFA rules regarding short flames. Not that it matters as I (and most of us) don't live there.
