From a distance, these look pretty good. They create a very bright yellow flame as they burn out.
The only problem is that they vary greatly between bills in the pack. Some work well, while others
are noticeably orange or too yellow. If you fold them just right, you can make the switch fairly
unnoticed (if you are using the newest design twenty dollar bill in your act). You'll have to keep
moving though, as any close examination will blow the illusion.
I must have got a better batch. mine look exactly like the real thing, even up close.
But I don't know how to switch it. no instructions come with it. I just tell people I have a new trick, it's called "Crazy" then I pull out the bill and light it on fire and say "wasn't
That crazy?"
