Is there a way to make the gimmicks using polymer money? We are quickly running out of paper money here, and US money will automagically be eyed suspiciously since you'll pretty much never see it here.

Will polymer bills fold correctly and will the see-thru window ruin it?

I really do think you are going to struggle with Polymer bills.
The fold of the bills is important.
Also I think the gimmick may show.

Canada has switched to this type of money and the old paper money is becoming more and more rare. I really like EB 2.0, but eventually using old 5s and old 20s will be odd. Also, does rubber glue stick as well to polymer as it does to paper? That see-through part of the new bills kind of makes this trick impossible.

The see through part is a problem, but does anyone know if this works with polymer bills? I think the R.C. might still work, but do the folds make that much of a difference?

There's a few things I was able to find out in the last 6 month.
Yes R.C. works perfectly fine on polymer notes. The folding part is more challenging. You might have to refold the bills every few month, just make sure you crease super hard with your nails.
So far it worked fine. I live in germany, europe and I hate euros.
2012 I lived in the US for a year and could perform every single bill change I ever wanted. So now that I'm back here I do extreme burn 2.0 with euros to pesos (my gf is mexican and euros to rumanian currency : lei. Both are polymer and the changes look insane - just the handling is slightly different. Try it out guys!!

Regarding the window - it can be a huge advantage when it comes to displaying the bills. When you make the gimmick, make sure both layers of the window are just on top of each other. When you display it - they swear its a single bill.

Hi there, so I'm not too clear on this too. Would I be able to create an extreme burn gimmick with the new Canadian bills. If anyone has tried it I would love to know your thoughts. Thanks!

For goodness sake, just grab some bills and try. What the heck do you suppose you'll gain by worrying yourself on the Café, when all it takes is 15 minutes to build up a set and learn how they work?
