Steve Mould is a science presenter and YouTuber who's just unmasked a Canadian currency feature that is so quantum-mechanically cool.
That when you shine a laser light through the maple leaf...
An encoded value of the bank note can be seen projected onto a blank surface.
For the $10 Steve used, it diffracted "$10, $10" around the central laser point.
The technology used in our money is called WinDOE®, a diffraction optical feature that forms an image when a specific light source passes through the feature. AKA it's a hologram of-sorts. AKA Coachella-Tupac-level-type shit.
OK not exactly. But how randomly neat, eh?
You can watch Steve's entire video below.
And let's not forget that — officially — nothing is too mundane or formal to pizzazz for the Canadian government.
Always a party.
