Build your own double slit experiment using the 3d pieces here plus one sewing needle, four M3x5 screws, and a laser pointer. I used 0.1 mm for the holder and 0.2 mm for everything else and printed in PLA with no supports. Set up the assembly 6 or more feet from a smooth white surface that can serve as a screen onto which the laser light can be projected. Shine light through the double slit and onto screen, if done correctly, you should see a series of light and dark bands on screen caused by the light waves diffracting through the slits and interfering with each other.
