Here's a short video of how to replicate the principles of lithography
using things you can find around your kitchen:
Click here to find the latest English version of the Handbook of Kitchen Lithography
which explains the process using the following ingredients:
Metal or plastic plate backing board, thick aluminium foil, Scotch tape,
Marseille soap (alkaline), paint brush, litho pencil,
Oil, Cola (or basic soda with phosphoric acid),
Roller, Oil-based etching ink, 2 sponges, basin or sink, water, paper
I loved that they also added this disclaimer:
Be careful: "simple" lithography don’t mean "easy".
You must take time to your dexterity to succeed.
