I remixed/Designed this lid to use in an electrolysis experiment - allowing the electrodes a safe distance and an amount of support to prevent the electrodes from contacting with one another. - It works much better than a piece of cardboard with holes punched in it; which is what i was using prior. :)
Fits wide mouth ball jars in USA.
