Cool Canadian money! Woo!

Hello LPF, it's been a bit since I started a thread. I want to show you guys something I've known about our money here for a while, but I thought it had been shared before. I guess not!
Our polymer plastic bills here are pretty neat:

Aside from being rainbow, waterproof, holographic, and yes, smelling slightly of maple, it's got one feature I'm really intrigued by. Lemme just grab a bill from my 'massive' stack of Queen Elizabeth's...

I'm just kidding, that wasn't very nice. So you see that little maple leaf above the 20, to the left of Your Majesty's hair? Well, not only does it smell more strongly of maple than the rest, but look at what happens when you shine a red laser through it:

It projects the value of the note onto the wall! Cool, huh? It's not just with the 20's though, it works with other bills too, like $50's:

$5's:

$10s and $100s too, but I don't have a hundred near me.

It works slightly well with yellow lasers, but mine is a bit too dim to look well ($20):

With green lasers, it gets more blurry:

And for good measure, here's blue which is not readable at all:

So the shorter the wavelength, the sharper the image. Interesting. Now I'm sure this wasn't designed this way with lasers in mind, it was actually designed I guess to be viewed through, looking at a small bright light source:

It looks much better to the eye rather than the camera
That's it, felt like I should share. Thanks for reading everybody!

That's so cool! With Euros we use UV lamps to determine whether a bill is real or not, so it must be the same with CAD then. Since you noticed it gets sharper the shorter the wavelength is, that must clarify why everyone (at least here) uses UV lamps.

Ah yeah, our old paper bills used to have UV dye on then, but the new bills don't. Those euros look very pretty under uv! I really like the fluorescent dye on our new passports, too

Polymer plastic? I guess no one is likely to run off copies of those and spend them. Personally I think we should go back to gold/silver/copper, but who wants to carry only coins.

Yeah I think they did a good job preventing counterfeiting. I wouldn't even know where to begin if I wanted to fake one...

I have to say that scented currency is one of the strangest ideas I have ever heard of. No doubt artificially scented with cancer causing chemicals. Do people in stores sniff them now to see that they are real?

Even the old ones were amazing in terms of bank note security.


Speaking of counterfeit technology I read an interesting article recently about why the US bank notes have not been kept up to date with other modern bank notes.
Quote:
David Wolman, author of The End of Money, explains that the legacy features that make US paper money look stale and anachronistic are meant to convey stability and timelessness. Since the U.S. economy is so important in the world economy, why mess with it? Some fear that changing the design of the currency significantly (or eliminating the penny) could undermine the faith in the Federal Reserve note.

Well, I don't think store clerks use it, but on a casual basis some people I know will smell money just cause, it's not a bad scent. The Bank of Canada insisted they added no smell, but just about everyone believes there is one. I think it's just an unintentional result of the composition.

That's pretty interesting, I really wondered why they didn't have some more snazzy bills, being America.
