It is not necessary to use all of those cards with punched holes.
Just pass the beam of a laser through a narrow slit and observe
the diffraction parttern that is produced. Each of the orders in
the diffraction pattern consists of identical waveforms

Repeating the process with the matter-wave-form of a "solid" object
such as an electron, or even a whole person, will produce a diffraction
pattern with several orders of constructive interference maxima.
Each of these patterns will have the same characteristics of the
original electron, or even the whole person.

Please do not explain to the students that there is no such thing.
The beauty of physics is that such things that were imagined in
the minds of past are present day realities now.
