How do you build a double-slit experiment at home?

Go out at night, hold the tips of your index finger and thumb lightly together, hold that out in front of you and look through the contact point between the tips at a distant light (street lights are good).

How does that have anything to do with the double slit experiment?

...because it shows an interference pattern; you may just look at it or take a picture.

Oh my gosh awesome how-to! Thanks for taking so much time to make it.

Thanks!

Firstly you need to use a monochromatic source such as a low power laser,or even a LED which is cheaper.
