I have discovered the secret.
OK, one secret. A secret. Just a small one, really.
I have discovered the secret to maximizing the beauty of a Crazy Eyeball firework.
And, well, yes, ok, I really should give part of the credit to Doug.
I am the happy codiscoverer of the secret to -- ah, you know.
Oh, yes, what is the secret. I suppose I really should get on to that. Yes, well, it's simple, really...
Set the Crazy Eyeball on the bottom of a tuna can. Choose one of the ones with a slight rim around the edge. Light the fuse, and get away.
Instead of a sputtering, not-quite-spin, or an off and on spin, you get a beautiful, fast, even spin, a glorious wheel of light around the center. It keeps the firework neatly in one place, too.
Doesn't work on Crazy Groundhogs. They're too energetic to be contained by the mild restraint of an inverted tuna can.
Do use an empty tuna can, too.
And now you know.
