Simple Way to Show Electron's Wave Properties?

[TheFalseHuman]

I was wondering is there is a simple way to show electron's wave properties, by using the double slit experiment as a reference.

What I think I need:

White Board that's reactive of electrons
Something with 2 slits
Something that can shoot out electrons

For something that can shoot out electrons, what would that be? Can I just have a Y-wire with one end open to shoot out the electrons?

I think the thing you're looking for is an electron gun. Even disassembling a very old TV-set (those really box looking ones) will yield one for you.

EDIT: on a secondary though, usually an oscilloscope also has an electron gun inside it

Be very careful if you decide to actually do that experiment. Those old TV-sets produce life threatening high voltages needed to accelerate the electrons.
