"Intuitive" means "consistent with prior experience". If that prior experience is using a prism in a box to take the spectrum of the sun or various kinds of electric lights, and then studying where the bright and dark bands come from? Or shining a laser pointer at a hair to see the diffraction pattern? Well, playing with that stuff for fun means that a lot of the QM stuff doesn't seem nearly as bizarre as it's said to be. But then, heavier-than-air flying machines were for a while considered impossible, rather than merely counterintuitive. And now you can get kits to make small ones at the toy store.
