Easy Homemade Printing

This is actually pretty amazing.  We saw this short video in Printmaking class and I want to try it, because it seems like items that one would usually have around the house or obtain fairly easily and cheaply: foil, handsoap, vegetable oil, soda, brayer, and ink.  If you made your image smaller you could run it through a pasta machine to print, too.  Except I only have ONE item in that list.  Go figure.  I never drink soda and we always use liquid soap instead of bar form.  :-<   *SO SAD.*  

I'm wondering if the soda could be substituted for a corn syrup/water mixture, since that is all Coca-Cola is anyway + fizz.
